A␣:See separation facto r.A solvent:Usually the weaker solvent in a binary eluent or gradient elution separation. In reversed-phase liquid chromatography (LC), the A solvent is typically water or a water-rich mixture.A term:The first term in the van Deemter equation.See eddy dispersion term and van Deemter equation.Absorption:The process of retention in which the solute partitions into a liquid-like coating.Activity:The relative strength of the surface of the packing in adsorption chromatography. For silica gel, the more available the silanol groups, the more active the surface. Activity can be controlled by adding water or another polar modifier that hydrogen bonds to the active sites, thereby reducing the surface activity.Additive:A substance added to the mobile phase to improve the separation or detection characteristics;for example, a competing base to negate the effects of silanols, a chelating agent to block metal sites or a UV-absorbing compound to perform indirect photometric detection.Adjusted retention time (t R Ј):A measure of the retention time adjusted for the hold-up time; t R Јϭt R Ϫt M , where t R is the retention time and t M is the hold-up time (the time it takes for a small,unretained compound that completely permeates the pores to be eluted from the chromatographic column).Adjusted retention volume (V R Ј):Adjusts the retention volume for the holdup volume; V R ЈϭV R ϪV M ,where V R is the retention volume of the peak of interest and V M is the hold-up volume (the volume corresponding to the total volume of mobile phase2GLOSSARY OF LIQUID-PHASE SEPARATION TERMSThe first glossary of common and not-so-common terms and buzzwords for reference to high performance liquid chromatography (HPLC) columns and column technology was published in 1988 (1). It is time for an update because•many new terms have arisen or, in some instances, their original meanings have expanded or changed•the various techniques of capillary electrophoresis (CE) have become well developed and are used in many laboratories throughout the world•the International Union of Pure and Applied Chemistry (IUPAC) published its massiveundertaking titled “Nomenclature for Chromatography,” which provides guidance and changes in some of the more commonly accepted terms (2).This booklet updates the earlier glossary and will expand coverage into techniques beyond HPLC. This glossary is not intended to be an in-depth or highly theoretical treatment. For example,we have elected not to cover the myriad terms used in instrumentation, detection, data handling,quantitative analysis and validation associated with liquid-phase analysis but instead have chosen to use terms that analysts may encounter in everyday laboratory work with columns, phases and method development. The listing should be helpful to those just starting in HPLC, CE and related techniques. It may also serve as a refresher for long-time users.LIQUID-PHASE SEPARATION TERMSGLOSSARY OFin the column). See also dead volume and hold-up volume.Adsorbent:Packing used in adsorption chromatography.Silica gel and alumina are the most frequently used adsorbents in high performance liquidchromatography (HPLC).Adsorption:The process of retention in which the interactions between the solute and the surface of an adsorbent dominate. The forces can be strongforces (hydrogen bonds) or weak (van der Waalsforces). For silica gel, the silanol group is the driving force for adsorption, and any solute functionalgroup that can interact with this group can beretained on silica. The term adsorption placesemphasis on the surface versus penetration orembedding in the stationary phase coated orbonded to a surface.Adsorption chromatography:One of the basic LC modes that relies upon adsorption to the surface of an active solid to effect the separation. Silica geland alumina are the most frequently used normal-phase adsorbents, and molecules are retained by the interaction of their polar function groups with the surface functional groups; for example, silanols of silica. Carbon is also used as an adsorbent in areversed-phase mode.Adsorption isotherm:A plot of the equilibrium concentration of sample in the mobile phase perunit volume versus the concentration in thestationary phase per unit weight in adsorptionchromatography. The shape of the adsorptionisotherm can determine the chromatographicbehaviour of the solute; for example, peak tailing, peak fronting and column overload.Aerogel:A packing prepared when the dispersing agent is removed from a gel system withoutcollapsing the gel structure. Silica gels and glassbeads used for size-exclusion chromatography (SEC) are examples of aerogels that can retain theirstructures even at the high pressures used in HPLC.See also xerogels.Affinity chromatography:A technique in which a biospecific adsorbent is prepared by coupling aspecific ligand — such as an enzyme, antigen orhormone — for the macromolecule of interest to a solid support (or carrier). This immobilized ligandwill interact only with molecules that can selectively bind to it. Molecules that will not bind will beeluted unretained. The retained compound can later be released in a purified state. Affinitychromatography is normally practised as an on–off separation technique.Agarose:High molecular weight polysaccharide used as a separation medium in biochromatography. It is used in bead form, often in gel-filtrationchromatography, with aqueous mobile phases. Alkoxysilane:A reactant used for the preparation of chemically bonded phases. It will react with silica gel as follows:R3SiOR ϩϵSiOH ¡ϵSi–OSiR3ϩROHwhere R is an alkyl group.Alumina:A normal-phase adsorbent used in adsorption chromatography. Aluminium oxide is a porousadsorbent that is available with a slightly basicsurface; neutral and acidic modifications can also be made. Basic alumina can have advantages oversilica, which is considered to have an acidic surface. Amino phase:A propylamino phase used in normal bonded-phase chromatography. It is somewhatreactive for solute molecules such as aldehydes ormobile-phase additives that can react with amines.The amino phase has found some applications as aweak anion exchanger, and it is also used for theseparation of carbohydrates with a water–acetonitrile mobile phase. It is a relatively unstable phase. Amphoteric ion-exchange resin:Ion-exchange resins that have both positive and negative ionic groups.These resins are most useful for ion retardation in which all ionic materials can be removed fromsolution because the anionic and cationicfunctionalities coexist on the same material. Analyte:The compound of interest to be analysed by injection into and elution from an HPLC column. Anion exchange:The ion-exchange procedure used for the separation of anions. Synthetic resins, bonded-phase silicas and other metal oxides can be analysed in this mode. A typical anion-exchange functionalgroup is the tetraalkylammonium, which makes astrong anion exchanger. An amino group on abonded stationary phase is an example of a weakanion exchanger.Asymmetry:Factor describing the shape of a chromatographic peak. Chromatographic theoryassumes a Gaussian shape and that peaks aresymmetrical. A quantitative measure is the peakasymmetry factor, which is the ratio of the distanceLC•GC Europe3C8:See octylsilane.C18:See octadecylsilane.C4, C8, C18etc.:Refer to the alkyl-chain length of a reversed bonded phase.C S:See Langmuir isotherm.Capacity:See sample capacity.Capacity factor (kЈ):Old term for a chromatographic parameter that measures the degree of retention.Now defined as the retention factor(k) by theInternational Union of Pure and Applied Chemistry (IUPAC). See also retention factor for method ofcalculation.Capillary column:Refers to columns with inner diameters less than 0.5 mm.Capillary electrochromatography (CEC):A hybrid technique in which capillary columns are packedwith chromatographic sorbents, and electroosmotic flow rather than pressure moves mobile phasethrough the column; technique has the surface-mediated selectivity potential of HPLC and the high efficiency of capillary electrophoresis (CE).Capillary gel electrophoresis (CGE):A technique in which a capillary is filled with, or the walls coated or covalently bonded with, cross-linked polyacrylamide to simulate slab gel electrophoresis; this polymernetwork uses a sieving mechanism; used for protein, carbohydrate and DNA separations such asfingerprinting and sequencing.Capillary isoelectric focusing:Separation is based on isoelectric points of proteins; the capillary is filledwith solution; the sample is introduced into thecapillary in the presence of ampholytes; under the application of an electric field, the protein migrates until it reaches a pH at which it is neutralized and maintains that position in the capillary.Capillary LC:Generally refers to HPLC performed in a fused-silica or other type of capillary column; theinner diameters are typically less than 0.5 mm; has also been called micro-LC.Capillary micellar electrochromatography:The CEC version of micellar electrokinetic capillarychromatography (MEKC).Capillary tubing:Tubing to connect various parts of a chromatograph and to direct flow to the properplaces.

The smallest useful inner diameter is approximately 0.004 in.Capillary zone electrophoresis (CZE):CE performed inan open fused-silica capillary tube with and without various additives and capillary coatings; also called open-tube capillary zone electrophoresis. Capping:Same as endcapping.Carrier:A term most often used in affinitychromatography; refers to the support that bindsthe active ligand, usually by a covalent bond; canalso refer to the support in other chromatography modes such as liquid–liquid chromatography. Carrier gas:The mobile phase in gas chromatography (GC).Cartridge column:A column type that has no endfittings and is held in a cartridge holder. Thecolumn comprises a tube and packing contained by frits in each end of the tube. Cartridges are easy to change and are less expensive and more convenient than conventional columns with endfittings.Cation-exchange chromatography:The form of ion-exchange chromatography that uses resins orpackings with functional groups that can separate cations. An example of a strong cation functionalgroup would be a sulfonic acid; a weak cation-exchange functional group would be a carboxylicacid.CE:Capillary electrophoresis.CEC:See capillary electrochromatography.CGE:See capillary gel electrophoresis.Chain length:The length of carbon chain in the hydrocarbon portion of a reversed-phase packing. It is expressed as the number of carbon atoms (C8, C18 etc.). It specifically excludes the short chains —typically methyl, isopropyl and sec-butyl groups —that are also attached to the silane.Channelling:Occurs when voids created in the packing material cause mobile phase and accompanyingsolutes to move more rapidly than the average flow velocity, which in turn allows band broadening to occur. The voids are created by poor packing orerosion of the packed bed.Chemisorption:Sorption caused by a chemical reaction with the packing. Most of these interactions areirreversible and usually occur on packings withreactive functional groups such as silanol or bonded amino phases. Chemisorption is common with metal oxide phases that have strong Lewis acid sites. Chiral recognition:The ability of a chiral stationary phase to interact differently with two enantiomers thereby leading to their HPLC separation.6GLOSSARY OF LIQUID-PHASE SEPARATION TERMSChiral stationary phases:Stationary phases that are designed to separate enantiomeric mixtures. Thephases can be coated or bonded to solid supports, created in situ on the surface of the solid support, or exist as surface cavities that allow specificinteractions with one enantiomeric form. Chlorosilane:A chemical reagent used to prepare siloxane bonded phases; reactivity changes from a monochlorosilane Ͻdichlorosilane Ͻtrichlorosilane;the alkyl portion (octadecyl, octyl, etc.) will dictate the hydrophobicity of the resulting bonded phase;alkoxysilanes can be used but are less reactive. Chromatogram:A plot of detector signal output or sample concentration versus time or elution volume during the chromatographic process. Chromatograph:As a noun: a device used to implement a chromatographic separation. As a verb (IUPAC): the act of separating by elution through a chromatographic bed.Classification:The process of sizing column packing particles; generally in HPLC, small particle-sizedistribution provides better efficiency and a greater permeability because of the absence of fines.Classification can be performed by sedimentation, elutriation and centrifugal air techniques.Column back pressure:See head pressure.Column chromatography:Any form ofchromatography that uses a column or tube to hold the stationary phase. Open-column chromatography, HPLC and open-tubular capillary chromatographyare all forms of column chromatography. Most often refers to open-column chromatography used forpreparative-scale work.Column length (L):The length of chromatography column in HPLC or capillary in CE used to perform the liquid-phase separation.Column performance (N):Refers to the efficiency of a column; the number of theoretical plates for a given test compound.Column plate number (N):Denotes the column efficiency; the larger the plate number, the moretheoretical plates the column possesses; a typicalwell-packed column with a 5 µm d p porous packing in a 15 cm ϫ4.6 mm column should provide10000–12000 plates.Column switching:Using multiple columns connected by switching valves for better chromatographicseparations or sample clean-up. Fractions from aprimary column can be switched to two or moresecondary columns, which in turn can be furtherdiverted to additional columns or to detectors;sometimes called multidimensional chromatography. Column volume (V c):The volume of the unpacked column; V cϭA c L, where A c and L are the cross-sectional area of the tube and the tube length,respectively.Competing base:Adding a small basic compound such as triethylamine or dimethyloctylamine at 10–50 mM concentration to the mobile phase in reversed-phase chromatography to inhibit basic analytes frominteracting with residual silanols; works by the law of mass action because concentration of competing base is much greater than analyte.

Controlled surface porosity support:Same as porous-layer bead and pellicular packing.Counter-ion:The ion in solution used to displace the ion of interest from the ionic site in an ion-exchange process. In ion pairing, it is the ion ofopposite charge added to the mobile phase to forma neutral ion pair in solution.Coupled columns:A form of column switching that uses a primary column connected to two secondary columns by a selector valve. Fractions from the first column can be selectively transferred to the second and third columns for additional separations. Thisterm is also used to describe two or more columns connected in series to provide an increased number of plates.Coverage:Refers to the amount of bonded phase on a silica support in bonded-phase chromatography.Coverage is usually described in micromoles persquare metre or in terms of percentage carbon(w/w).Critical micelle concentration:The concentration of an ionic surfactant above which a micelle is formed by aggregation; micelles added to a mobile phaseimprove the separation of non-ionic substances inHPLC and CE (MEKC) by a partitioning mechanism. Cross-linking:During the process of copolymerization of resins to form a three-dimensional matrix, adifunctional monomer is added to form cross-linkages between adjacent polymer chains. Thedegree of cross-linking is determined by the amountLC•GC Europe7of the monomer added to the reaction. Forexample, divinylbenzene is a typical cross-linkingagent for the production of polystyrene ion-exchange resins. The swelling and diffusioncharacteristics of a resin are governed by its degree of cross-linking.Cyclodextrins:Cyclic oligomers of several D-(ϩ)-glucopyranose units used in chiral HPLC and CEseparations; popular ones are named ␣-, - and ␥-cyclodextrins; they have a truncated cone shape, a relatively hydrophobic cavity, and primary andsecondary hydroxyl groups at their ends; theyseparate on the basis of differential inclusion ofenantiomers; modified cyclodextrins withderivatized hydroxyl groups are also used forselectivity modification.CZE:See capillary zone electrophoresis.DDead volume (V M):The column dead volume comprises the entire space accessible to a small molecule that can fully permeate all pores of a packing material. It includes the interstitial volume and the unoccupied pore volume. It is denoted as V M. The system dead volume includes the additional volume in the tubing that connects the injector and detector to thecolumn. The system dead volume is usuallyestimated by injecting a small, essentially unretained species. Uracil, acetone and thiourea are mostcommonly used species in reversed-phasechromatography. See also adjusted retentionvolume,hold-up volume and void volume.DEAE:See diethylaminoethyl.Degassing:The process of removing dissolved gas from the mobile phase before or during use. Dissolvedgas may come out of solution in the detector celland cause baseline spikes and noise. Dissolved aircan affect detectors such as electrochemical (byreaction) or fluorescence (by quenching) detectors.Dissolved gases can also cause pumps to lose their prime. Degassing is performed by heating thesolvent, helium sparging or using vacuum (in avacuum flask) or on-line evacuation from a tubemade of a gas-permeable substance such aspolytetrafluoroethylene (PTFE).Denaturing HPLC:Using reversed-phase HPLC to investigate genetic mutations by the investigation of DNA base pairs.Desalting:Technique in which low molecular weight salts and other compounds can be removed fromnon-ionic and high molecular weight compounds.An example is using a reversed-phase packing toretain sample compounds by hydrophobic effectsyet allowing salts to pass through unretained. Using an SEC column to exclude large molecules andretain lower molecular weight salts is anotherexample.Dextran:Polydextran-based packing material primarily used for low-pressure biochromatography; anexample is Sephadex (Amersham Pharmacia Biotech, Roosendaal, The Netherlands).Diethylaminoethyl (DEAE):A popular weak anion-exchange functionality (typically attached tocellulose or Sepharose [Amersham PharmaciaBiotech]) used for separating biomolecules. Diffusion coefficient (D M or D S):A fundamental parameter of a molecule in gas, solution (D M) orstationary phase (D S). Expressed in squarecentimetres per second.

It is a diol structure(two –OH groups on adjacent carbon atoms in analiphatic chain). In normal-phase work, it is lesspolar than silica. It has been used to separateproteins and polypeptides in reversed-phasechromatography.Displacement chromatography:A chromatographic process in which the sample is placed onto thecolumn head and is then displaced by a compound that is more strongly sorbed than the compounds of the original mixture. Sample molecules are thendisplaced by each other and by the more stronglysorbed compound. The result is that the elutedsample solute zones may be sharpened;displacement techniques have been used mainly in preparative-scale HPLC applications.Distribution constant (coefficient) (K c):The total equilibrium concentration of a component in allforms or on the stationary phase divided by thetotal equilibrium concentration of the component in the mobile phase; also called the distribution8GLOSSARY OF LIQUID-PHASE SEPARATION TERMScoefficient or the partition coefficient in partitionchromatography. In partition chromatography, K c is used when the concentration in the stationaryphase is expressed per unit volume of the phase (V RϭV MϩK c V S). In a solid stationary phase, K g is used and is expressed per mass (weight) of the dry solid phase. In adsorption chromatography with awell-characterized adsorbent of known surface area, the concentration in the stationary phase isexpressed per unit surface area.D M:See diffusion coefficient.d p:See particle size.D S:See diffusion coefficient.Dwell time:The time equivalent to dwell volume;determined by the product of flow-rate and thedwell volume.Dwell volume:The volume between the point of mixing of solvents (usually in the mixing chamber or at the proportioning valves in the liquidchromatograph) and the head of an LC column.Important in gradient elution or in isocratic elution situations when changes in solvent composition are made so that the column experiences thecomposition change in the shortest possible time.Low-pressure mixing systems generally have larger dwell volumes than high-pressure mixing systems. Dynamic coating:The formation of in-situ coatings on the packing in HPLC or on capillary walls in CE byadding a substance to the mobile phase thatadsorbs onto (or absorbs into) the packing or at the wall surface. The purpose of a dynamic coating is to generate a new stationary phase or to deactivatethe packing material or capillary wall to preventunwanted interactions. One simple example is the adjustment of the mobile phase or running buffer to less than pH 3 to protonate silanols and negate their effect. Another example is coating the phase with a hydrophilic polymeric material to preventadsorption of proteins.E:See interparticle porosity.E:See separation impedance.Eddy dispersion (diffusion) term ():The A term in the van Deemter equation. It is the contribution to plate height from the heterogeneity in axial velocities as a result of the particle size and geometry of thepacking, as well as wall effects; A ϭ2d p, where isan empirical column constant. Typical values of for well-packed columns are 0.8–1.0. Some theories of chromatography indicate a velocity-dependentcontribution to the height equivalent to atheoretical plate (HETP) from this process. Alsoknown as eddy diffusion, flow-heterogeneityinduced broadening, and the multipath term. Seealso van Deemter equation.e:See interstitial porosity.Effective capillary length: The distance between the point of sample addition and the point of detection in CE. For on-capillary detection in which thecolumn is used as the flowcell in UV detection, this length is shorter than the capillary length.Effective plate height (H eff):The column length divided by the effective plate number.Effective theoretical plates (N eff):Also called the effective plate number by IUPAC. The true number of plates in a column, because it corrects theoretical plates for dead volume. N effϭ16[(t RЈ/w b)2], where t RЈis the adjusted retention time and w b is thebandwidth of the peak (see Figure 2). It is a better figure of merit than simple plate number forcomparing devices of very different geometries and phase ratios.Efficiency (N or H):A measure typically determined by the number of theoretical plates (N) calculated from the equation Nϭ16(V R/w b)2ϭ16(t R/w b)2, wherew b is the peak width measured at the base (seeFigure 2). If the peak width is measured at halfheight (w h), the following equation is used: Nϭ5.545 (V R/w h)2. The plate height (H) or HETP isdetermined by HϭL/N. The efficiency of asymmetric peaks is better determined from the peak centroid and variance by mathematical analysis of the peak shape. See also Foley–Dorsey equation.Effluent:The mobile phase leaving the column; same as eluate.i:See intraparticle porosity.Electroendosmotic flow:See electroosmotic flow. Electromigration injection:Inlet end of CE capillary is placed in sample solution and voltage is applied fora set time; analytes move from sample vial intocapillary; discrimination effects may occur because compounds of differing charges will migrate atdifferent rates.Electroosmotic flow (v eo):Bulk flow of solvent within capillary caused by presence of zeta potentialLC•GC Europe9(electric charge) at the capillary walls and absence of flow resistance. Most likely source of zetapotential is presence of ionized silanols at the fused-silica surface or intentional coating of the capillary wall with an ionic phase. Depending upon zetapotential, electroosmotic flow may be towardsanode or cathode and contributes to overallretention in CE techniques.Electrophoresis:The movement of sample ions under the influence of an applied voltage. Electrophoretic mobility (µ):Characteristic of a given ion in a given medium and at a given temperature in CE analyses; proportional to the charge of ionand inversely proportional to solution viscosity and the ion’s radius.Eluate:Combination of mobile phase and solute exiting the column; also called effluent.Eluent:The mobile phase used to perform aseparation.Eluite:The species being eluted, the analyte or the sample.Eluotropic series:A series of solvents (eluents) with an increasing degree of solvent strength generally used in liquid–solid or adsorption chromatography. Innormal-phase chromatography, a non-polar solvent such as pentane would be at the low end of thescale, an intermediate solvent such as methylenechloride would be in the middle of the scale, and a strongly polar solvent such as methanol would benear the upper end of the scale. In reversed-phase chromatography, the reverse order of strengthwould be observed; water would be weak andacetonitrile strong. Thus, when developing amethod or running a gradient, an eluotropic series is useful for selecting solvents. See also Snydero. Elute:To chromatograph by elution chromatography.The term elute is preferred over develop, which was used in older nomenclature.Elution:The process of passing mobile phase through the column to transport solutes down a column. Elution chromatography:The most commonly used chromatographic method in which a sample isapplied to the head of the column as a narrow zone and individual analytes are separated and elutedfrom the end of the column. Compare withdisplacement chromatography and frontal analysis. Elution volume (V R):Refers to the volume of mobile phase necessary to elute a solute from a column. Itis the volume from the point of injection to thevolume at maximum concentration (apex) for a symmetrical peak; V RϭFt R, where F is the flow-rate and t R is the retention time of the peak of interest. Elutriation:A technique used to fractionate packing particles by size based on the difference in theirStokes terminal velocities. It is most often used for the separation of ion-exchange resins that require a particularly narrow size range, such as amino acid resins. The technique involves the upward flow of water into a large tube. The unsized beads areadded to the moving water, and the particles seek their own level, depending upon their density and particle size. They are removed at certain levels in the tube. High-purity spherical silica gels aresometimes sized by elutriation.Endcapping:A technique used to remove silica gel silanol groups that may remain after reaction with a large silylating agent such as octadecyltrichlorosilane.The column is said to be endcapped when a small silylating reagent (such as trimethylchlorosilane or dichlorodimethylsilane) is used to bond residualsilanol groups on a silica-gel–based packing surface.Most often used with reversed-phase packings tominimize undesirable adsorption of basic, ionizable and ionic compounds. Endcapping reactions are also used to remove terminal silanol groups frompolymeric phases.Endfitting:The fitting at the end of the column that permits connection to the injector or detector. Most HPLC endfittings have frits to contain the packing and low dead volumes for minimum bandspreading. They are usually constructed of stainless steel, but polyetheretherketone (PEEK) and otherpolymeric materials are also used. Enzymophoresis:A tandem format in which a short fused-silica capillary containing immobilized enzyme on the inner wall is coupled with a CZE capillary; an enzymatic reaction occurs with the injected sample, and the products and unreacted substances enterthe separation capillary; used to improveseparations, detection or analyte preconcentration.T:See total porosity.Exchange capacity:See ion-exchange capacity. Excluded volume:See interstitial volume.Exclusion chromatography:See ion-exclusion chromatography and steric exclusionchromatography.10GLOSSARY OF LIQUID-PHASE SEPARATION TERMS。

Abstract:Column packings continue to evolve as the needs of users for high efficiency,high resolution and highly sensitive high performance liquid chromatographic(HPLC)analysis drive further developments.In corn— parmg and contrasting modern HPLC columns technologies,diameters of column packings and particle materi。 als are covered.Some products and applications of modem HPLC columns are provided.Future directions in packing developments are predicted in this introductory article. Key words:high performance liquid chromatography(HPLC);column packings;silica particles CLC number:O658 Document code:A Article IC:1000—8713(2011)0l一0003—03
The last six years have seen three competing col— umn technologies(sub 2 m column packings, Halo column packings and monolithic column technology)try to supplant the status quo in high performance liquid chromatographic(HPLC)col— umns.For the record,the baseline until early 2005 was packed bed columns using 3 LLm spheri— cal porous column packings.These can provide about l 0 000 plates in a l 5 cm long reversed phase column.Other phase chemistries,or modes such as ion exchange often offer less efficiency and lower peak capacity.However,most chromatog— raphers would prefer to use columns with the best available efficiency,since this is directly related to the ease in achieving a separation of interest. Yes,one can often improve separations by loo— king for optimum separation selectivity,but the current state of the art makes this search mostly empirical and hence time consuming.Most of the computer aided simulation software such as DryLab[1]starts with an experimental run or two with a particular stationary and mobile phase,and then expands this empirical base case using well developed extrapolations.Ab initio prediction of chromatographic separation without resorting to empirical or calibration reference points is still mostly a dream,especially as the molecular complexity increases. To date,most of the leading research on new col— umn packings occurs in the occidental world.For LC instruments,China is probably the second lar— gest market behind the USA,but the number of cutting edge research papers is small,although these are increasing significantly.So let’s look at the consensus on column technology that is devel— oping in the occidental world.This is based pri— marily upon lectures presented by Mr.Jupille[2] (LC Resources.Walnut Creek,CA)and Prof. Paull[3](Dublin City University,Dublin,IR). The general correlation of improved efficiency and speed with reducing the diameter of column pack— ings is well known(Table 1).Reducing the size by a factor of two usually improves efficiency by more than twice,but at the expense of back pres— sure,which quadruples with the two fold size reduction.In the mid l 990’s firms such as Micra Scientific(Now Eichrom,Darien. IL) and Bischoff Chromatography(Stuttgart,Germany) introduced column packings with diameter as small as 1.5 LLm.These failed to win user accept— ante,since the instrumentation(fittings,pumps and injectors)was too limited in pressure and detector response time.In 2004,Waters introduced the ultra hilgh performance liquid chromatographs

All columns have the same dimension(1 50 nlln x 4.6 nln1. eluted with 60%acetonitrile at 1 mL/min.35℃].In practice most HPLC separations require only l 0 000 plates.Thus.it is often possible to reduce the column length as the particle size decreases.This saves time and reduces the required pres* st】re What about more efficiency from even smaller particles than 1.7 m?A recent report by Prof. Wirth(Purdue University,Lafayette,IN)at HPLC 201 0 in Boston,reported IO0 m i.d.cap— illaries packed with 50 nm silica particles.These generated very high efficiency(plate heights of 1 00 RE for proteins and 300 nm for small mole— cules) using electrochromatography(CEC). Since the columns are also very short(~1.5 em),the pressure drop and frictional heating are manageable.Column plate count is 1 50 000 to 50 000 plates. The global installed base of UHPLC capable in— struments is about l 8 000 and growing by several thousand per year.In contrast,the number of active HPLC Instruments with pressure rating of 6 000 psi or so,is about 300 000.These are called legacy instruments since the technology really dates from the 1 970s,but these give very good performance and excellent reliability,especially if one does not need the ultimate in detection sensi— tivity and speed offered by the UHPLCs. Dr.Kirkland『4 1 of Advance Material Technolo gies(Wilmington DE)dusted off some technolo— gY from the 1960s called Zipax@[5]which fea— tured a porous layer of stationary phase around a solid core of 35 LLm diameter silica.The thin active surface provided rapid mass transfer,and the large particles made the columns easy to pack.Typical columns were 1 m long and ran at only a few hundred psi.He shrunk the size of the solid core to 1.7 LLm and added a porous surface silica surface.These are now called“Halo”col— umn packings.They sacrifice some of the column capacity due to the solid core,but mass transfer in and out of the column packing is fast,so effi— ciency is high.The main feature is that the parti— cle diameter is very close to 3 ixm,which is about the limit that is useful with legacy(6 000 psi) instruments.Halo columns provide a significant improvement in efficiency and resolution over the corresponding column packed with 3 m porous particles,and at the same pressure drop.And, with the large installed base of legacy instru— ments,these columns are quite popular. Monoliths are the third emerging,potentially competitive HPLC column technology.The open bed structure of both the silica and polyineric monoliths offers excell6nt efficiency(comparable to good quality columns packed with 3 txm parti— cles)but require only about 1 5%of the pressure for comparable length and flow rate.This means that one can use longer colunms before running up against the pressure limit of the instrument. And,longer columns give more plates and hence reso】utjon.
