Terms and their definitionsAccuracy 准确度A measure of the agreement betweenan experimental result and its expected value. Analysis 分析A process that provides chemical or physicalinformation about the constituents in the sampleor the sample itselfAnalyte 被测物,被分析物The constituent of interest in asampleCalibration curve 校准曲线The result of a standardizationshowing graphically how a method’s signalchanges with respect to the amount of analyte. Calibration method 校准方法The basis of quantitative analysis:magnitude of measured property is proportional toconcentration of analyteChromophore 生色团 A functional group which absorbs acharacteristic ultraviolet or visible wavelength Gradient elution 梯度洗脱The process of changing the mobilephase’s solvent strength to enhance the separationof both early and late eluting solutes. Gravimetric analysis重量分析A type of quantitative analysis in whichthe amount of a species in a material is determinedby converting the species into a product that can beisolated and weighed.Isocratic elution 等度洗脱the use of a mobile phase whosecomposition remains constant throughout theseparation.Matrix 基质All other constituents in a sample except forthe analytesMethod blank 方法空白A sample that contains all componentsof the matrix except the analyte.Outlier 离群值Data point whose value is much larger orsmaller than the remaining data.Precision 精密度An indication of the reproducibility of ameasurement or resultQuantitative analysis 定量分析The determination of the amount of asubstance or species present in a material. Quantitative transfer 定量转移The process of moving a sample fromone container to another in a manner that ensures allmaterial is transferred.Selectivity 选择性 A measure of a method’s freedom frominterferences as defined by the method’s selectivitycoefficient.Significant figures 有效数字The digits in a measured quantity,including all digits known exactly and one digit (thelast) whose quantity is uncertain. Spectrophotometry 分光光度法. An analytical method that involveshow light interacts with a substanceStock solution 储备液 A solution of known concentrationfrom which other solutions are prepared. Titration curve 滴定曲线 A graph showing the progress of atitration as a function of the volume of titrant added. Validation (方法)确证,验证The process of verifying thata procedure yields acceptable results.Titration error 滴定误差The determinate error in a titration due tothe difference between the end point and theequivalence point.Robust method 广泛适用的方法A method that can be applied toanalytes in a wide variety of matricesRugged method 稳健的方法 A method that is insensitive to changes inexperimental conditionsMass Spectrometry 质谱法An analytical method which is based on ionization ofgas phase molecule followed by analysis of the masses of theions producedIII.
