常用VOC测试方法VOC测试方法通常分为两种：一种是快速出数据的PID检测法，一种是气相色谱法快速出数据的PID检测法快速出数据的PID检测法通常采用的紫外灯是充有氢气或氢气等气体的辉光放电管。
辐射能量为１０．２ｅＶ的紫外灯充有０．１－１托的氢气，在直流高压的电场作用下电极间产生辉光放电，形成长约１０厘米，直径１厘米的等离子体柱。
紫外灯用玻璃外壳，窗口处由透射晶片胶封。
电极可用铂、铭、钨等材料。
voc有机气体检测仪电极的形式和几何尺寸、灯内充气压力都会影响紫外光谱上能量的分布状况。
紫外灯辐射的紫外光波长和能量取决于灯内所充的气体。
通常使用能量为９．５ｅＶ，１０．２ｅＶ，１１．７ｅＶ三种紫外灯。
采用这几种灯时，voc有机气体检测仪分析物质的范围可从物质分子的电离能数据来判断。
凡电离能小于光源能量的物质均能被电离和分析，电离能大于光源能量的物质则不能。
实验表明样品分子的电离能若比光源能量大０．３ｅＶ以上，就只有很小的PID响应。
如果要得到足够的响应，样品电离能至少应比光源能量低０．３ｅＶ。
１０．２ｅＶ光源能电离的样品物质范围较宽，（包括所有的芳香烃、酮类、杂环碳氢化物、胺类），绝大多数不饱和化合物以及一些无机化合物（如硫化氢、磷化氢、氨、碘、滨等），因此用得最多。
voc有机气体检测仪它所发射的氢分子光谱带中，以波长为１２１６入的ｌｙａ线最集中，其他波长的杂散光很少，因而这种光源强度很高，比９．５ｅＶ，１１．７ｅＶ光源强４一１０倍，灵敏度也最高。
９．５ｅＶ voc有机气体检测仪光源辐射能量较低，能电离的物质范围相应要小一些，因而也有一个好处，即有较多的物质不会被电离，故可选用作样品的溶剂组份较多。
１１．７ｅＶ光源辐射能量较高，能电离的物质范围很宽，包括所有的链烷烃（除甲烷外）类、卤化碳类（如四氯化碳和氯仿等）、有机酸类（如甲酸、乳酸）及甲醛等，适宜分析电离能在１０．２＾－１１．７ｅＶ之间的各种物质。
缺点是可选作样品溶剂的物质很少。

汽车VOC测试方法介绍1.气瓶法（Canister Method）：这种方法是将汽车尾气收集到气瓶中进行分析。
首先，气瓶通过干扰气体的通气装置进行预气。
然后，气瓶通过溢流阀与汽车尾气接触，吸收其挥发有机物。
接下来，将气瓶连接到分析系统中，使用气相色谱-质谱联用仪（GC-MS）进行挥发有机物的分析和检测。
这种方法具有简单、可靠、高灵敏度等优点，但需要较长的时间进行采样和分析。
2.袋装法（Bag Method）：这种方法是将汽车尾气收集到塑料袋中进行分析。
首先，在汽车排气管上安装一个塑料袋。
然后，将排气管直接从汽车尾气中捕集无需额外的仪器。
接下来，使用特定的采样袋将汽车的尾气收集，并将其送入实验室进行GC-MS分析。
这种方法具有简便、经济、快速的特点。
3.源排放口测量法（Source Emission Measurement Method）：这种方法是直接在汽车的排放口进行测量和分析。
首先，使用专用的底片对尾气进行采样。
底片上的有机物吸附在其表面，然后可以在实验室中使用热脱附技术进行分析。
这种方法通常能够获取更准确的数据，但需要专业的设备和技术。
4.车内空气采样法（In-Cabin Air Sampling Method）：这种方法是在汽车内部进行空气采样和分析。
首先，在汽车内部放置采样装置，例如吸附剂管或吸附剂循环系统。
然后，使用气相色谱法或液相色谱法对被吸附有机物进行测量。
这种方法可以直接了解人体暴露的情况，但需要较长的采样时间。
在进行汽车VOC测试时，还需要注意以下几个方面：1.选择适当的采样位置：根据测试的目的和要求，选择适当的采样位置是非常重要的。
一般来说，可以选择汽车排气管的近侧或远离源排放口的位置进行采样。
2.采样过程中的注意事项：在进行汽车VOC测试时，需要注意避免外部干扰对采样结果的影响。
例如，在进行气瓶法或袋装法时，需要注意排气管的保持清洁，以避免其他物质的污染。
3.检测仪器的选择和校准：选择适当的仪器对VOC进行检测是非常重要的。
定义：挥发性有机化合物（ Volatile Organic Compounds/VOCs ）是一种在常温常压下，具有高蒸气压和易蒸发性能的有机化学物质。
挥发性有机物污染多属于逸散性排放，倘若被散发于环境中逸散至大气后经阳光照射会与氮氧化物产生臭氧浓度上升及光化学烟雾等环境污染问题，便会对人体健康造成潜在的威胁，包括刺激眼睛和呼吸管道、头疼等，而且，当中某些化学品如苯、甲苯、三氯苯、卤化碳卤代烯烃（三氯乙烯、二氯乙烯）等已被怀疑或确定为致癌物质。
挥发性有机物的来源主要为石油产品、化学溶剂、汽车尾气和燃烧废气。
石油产品主要存在于石油、化工、加油站等生产和销售单位，而化学溶剂则同每个人的生活密切相关，无论是纺织品、鞋类、化妆品、油漆、家具、办公用品、室内装饰还是电子电器等设备都可能产生挥发性的有机物质。
电子产品在使用中常常会有部分的零组件会处于高温，在此加温状态上容易逸散出苯等挥发性有机物质 (VOC) 的异味。

The Executive Officer will maintain sample chain of custody throughout the selection and analytical process.3.2 Initial Testing of Aerosol ProductsIf the sample is an aerosol product, the aerosol propellant is separated from the non-propellant portion of the product by using ASTM D 3074-94 (as modified in Appendix A for metal aerosol container) or ASTM D 3063-94 (as modified in Appendix A for glass aerosol container). The propellant portion is analyzed for exempt or prohibited compounds by using US EPA Reference Method 18. The remaining non-propellant portion of the product is then analyzed as specified in section 3.3.3.3 Initial Testing of Non-Aerosol Products and the Non-Propellant Portion of AerosolProductsThe non-aerosol product or non-propellant portion of an aerosol product is analyzed to determine the total volatile material present in the sample and to determine the presence of any exempt or prohibited compounds. This analysis is conducted by performing the following tests:13.3.1 Gravimetric analysis of samples to determine the weight percent of total volatilematerial, using US EPA Reference Methods 24/24A, ASTM D 2369-01.3.3.2 Determination of sample water content. For determination of water content eitherASTM D 4017-96a, or ASTM D 3792-99 may be used, or results from bothprocedures may be averaged and that value reported.1Alternate test methods may be used, as provided in section 7.03.3.3 Determination of ammonium content using ASTM D 1426-98 or US EPA Method300.7.3.3.4 Determination of ketones and alcohol content using NIOSH Method 1400.3.3.5 Analysis of exempt and prohibited compounds, if present (US EPA ReferenceMethod 18, US EPA Method 8240B, US EPA Method 8260B, ASTM D 859-00,NIOSH Method 1400).3.3.6 If LVP-VOC status is claimed or the analysis indicates the presence of an LVP-VOCcomponent and the percent VOC is not in compliance, the Executive Officer willrequest formulation data as specified in Section 3.5.2.3.3.7For low level VOC content samples, direct determination using US EPA ReferenceMethod 18, US EPA Method 8240B, US EPA Method 8260B, ASTM D 859-00,NIOSH Method 1400.3.3.8 For aromatic compound content determination, US EPA Method 602, US EPA SW-846 Method 8020A, US EPA Modified Method 8015, US EPA Method 625, US EPAMethod SW-846 Method 8270D, ASTM D 5443-04, ASTM D 3257, ASTM D 3710-95, ASTM D3606-07, ASTM D 5580-02.3.4 Prohibited CompoundsIf the sample is found to contain compounds prohibited by ARB regulations (i.e., ozone-depleting compounds) at concentrations equal to or exceeding 0.1 percent by weight, the Executive Officer will reanalyze the sample for confirmation.3.5 Initial Determination of VOC ContentThe Executive Officer will determine the VOC content pursuant to sections 3.2 and 3.3.Only those components with concentrations equal to or greater than 0.1 percent by weight will be reported.3.5.1 Using the appropriate formula specified in section4.0, the Executive Officer willmake an initial determination of whether the product meets the applicable VOCstandards specified in ARB regulations. If initial results show that the product doesnot meet the applicable VOC standards, the Executive Officer may perform additionaltesting to confirm the initial results.3.5.2 If the results obtained under section 3.5.1 show that the product does not meet theapplicable VOC standards, the Executive Officer will request the productmanufacturer or responsible party to supply product formulation data. Themanufacturer or responsible party shall supply the requested information.Information submitted to the ARB Executive Officer may be claimed as confidential;such information will be handled in accordance with the confidentiality proceduresspecified in Title 17, California Code of Regulations, sections 91000 to 91022.3.5.3 If the information supplied by the manufacturer or responsible party shows that theproduct does not meet the applicable VOC standards, then the Executive Officer willtake appropriate enforcement action.3.5.4 If the manufacturer or responsible party fails to provide formulation data as specifiedin section 3.5.2, the initial determination of VOC content under this section 3.5 shalldetermine if the product is in compliance with the applicable VOC standards. Thisdetermination may be used to establish a violation of ARB regulations.3.6 Determination of the LVP-VOC status of compounds and mixtures. This section doesnot apply to antiperspirants and deodorants or aerosol coatings products because there is no LVP-VOC exemption for these products.3.6.1 Formulation data. If the vapor pressure is unknown, the following ASTM methodsmay be used to determine the LVP-VOC status of compounds and mixtures: ASTMD 86-01, ASTM D 850-00, ASTM D 1078-01, ASTM D 2879-97, as modified inAppendix B to this Method 310, ASTM D 2887-01 and ASTM E 1719-97.3.6.2 LVP-VOC status of “compounds” or “mixtures.” The Executive Officer will test asample of the LVP-VOC used in the product formulation to determine the boilingpoint for a compound or for a mixture. If the boiling point exceeds 216o C, thecompound or mixture is an LVP-VOC. If the boiling point is less than 216o C, thenthe weight percent of the mixture which boils above 216o C is an LVP-VOC. TheExecutive Officer will use the nearest 5 percent distillation cut that is greater than216o C as determined under 3.6.1 to determine the percentage of the mixturequalifying as an LVP-VOC.3.6.3 Reference method for identification of LVP-VOC compounds and mixtures. If aproduct does not qualify as an LVP-VOC under 3.6.2, the Executive Officer will testa sample of the compound or mixture used in a product’s formulation utilizing one orboth of the following: ASTM D 2879-97, as modified in Appendix B to this Method310, and ASTM E 1719-97, to determine if the compound or mixture meets thedefinition of LVP-VOC as specified in Title 17, CCR, section 94508(a).3.7 Final Determination of VOC ContentIf a product’s compliance status is not satisfactorily resolved under sections 3.5 and 3.6, the Executive Officer will conduct further analyses and testing as necessary to verify the formulation data.3.7.1 If the accuracy of the supplied formulation data is verified and the product sample isdetermined to meet the applicable VOC standards, then no enforcement action forviolation of the VOC standards will be taken.3.7.2If the Executive Officer is unable to verify the accuracy of the supplied formulation data, then the Executive Officer will request the product manufacturer or responsible party to supply information to explain the discrepancy.3.7.3 If there exists a discrepancy that cannot be resolved between the results of Method310 and the supplied formulation data, then the results of Method 310 shall take precedence over the supplied formulation data. The results of Method 310 shall then determine if the product is in compliance with the applicable VOC standards, and may be used to establish a violation of ARB regulations.4 CALCULATION OF VOC CONTENTThis section specifies the procedure for determining the final VOC content of a product, which is reported as percent by weight of VOC.4.1 Aerosol Products4.1.1 For aerosol products, except those containing LVP-VOC, the percent VOC contentshall be calculated using the following equation:Where 2:WL = weight (gm) of the non-propellant portion, excluding container andpackaging.TV = weight fraction of non-propellant total volatile material.A = weight fraction of ammonia (as NH 4) in the non-propellant portion.H = weight fraction of water in the non-propellant portion.EL = weight fraction of exempt compounds in the non-propellant portion.WP = weight (gm) of propellant.EP = weight (gm) of exempt compounds in propellant.4.1.2 For aerosol products containing LVP-VOC, the percent VOC shall be calculated usingthe following equation:2Alternate test methods, as provided in section 7.0, or appropriate approved methods from section 2.0 may be used.100WPWL EP WP )EL H A TV (WL VOC %⨯+-+---=Where:LVP = weight fraction of LVP-VOC compounds and/or mixtures in the non-propellant, non-aqueous portion.1 – H = weight fraction of the non-propellant portion that does not containwater.1 – LVP= weight fraction of the non-propellant, non-aqueous portion that isvolatile.4.2 Non-Aerosol Products4.2.1 For non-aerosol products, except those containing LVP-VOC , the percent VOCcontent shall be calculated using the following equation:4.2.2For non-aerosol products containing LVP-VOC, the percent VOC shall be calculated using the following equation:4.2.3For Fabric Softener – Single Use Dryer Product, the grams of VOC per sheet shall be calculated as follows:Total Grams VOC perSheetWhere:S = mass, in grams, of the dryer sheet sample.R = mass, in grams, of sample residue by gravimetric analysis.D = mass, in grams, of the single dryer sheet.4.3Consumer products subject to low VOC limits (below 5.0%) may have their VOC content characterized by a low level direct determination.4.3.1 For aerosol products the percent VOC content may be calculated using the followingequation:))(([])(100WPWL EP WP EL LVP 1H 1WL VOC %⨯+-+--⨯-=100)EL H A TV (VOC %⨯---=)()([]100EL LVP 1H 1VOC %⨯--⨯-=D S R S ⨯-=Where:V = weight fraction of non-exempted volatile organic compounds in the non-propellantportion.n = number of non-exempted volatile organic compounds in the non-propellant portion.WL = weight (gm) of the non-propellant portion, excluding container and packaging.WP = weight (gm) of propellant.EP = weight (gm) of exempt compounds in propellant.4.3.2 For non-aerosol products the percent VOC content shall be calculated using thefollowing equation:[]100%⨯=∑nV VOC5 TESTING TO DETERMINE REACTIVE ORGANIC COMPOUNDS IN AEROSOLCOATING PRODUCTSThis section specifies the procedure for determining the percent by weight of the reactive organic compounds contained in aerosol coating products, for the purpose of determining compliance with the Aerosol Coatings Regulation.5.1 The testing begins when the Executive Officer selects a product for analysis. TheExecutive Officer will maintain sample chain of custody throughout the selection and analytical process. When a product is selected for testing, the Executive Officer will request the product manufacturer or responsible party to supply the product formulation data specified in Title 17, CCR, section 94526(b)(2). The manufacturer or responsible party shall supply the requested information within 10 working days. Information submitted to the Executive Officer may be claimed as confidential; such information will be handled in accordance with the confidentiality procedures specified in sections 91000 to 91022, Title 17, CCR.5.2 Initial Testing of the Propellant Portion of Aerosol Coating ProductsThe aerosol propellant is separated from the non-propellant portion of the product by using ASTM D 3074-94 (as modified in Appendix A for metal aerosol container) or ASTM D 3063-94 (as modified in Appendix A for glass aerosol container). The propellant portion is analyzed for reactive organic compounds and other compounds by []100%⨯+-+=∑WPWL EP WP V WL VOC nusing US EPA Reference Method 18. The remaining non-propellant portion of the product is then analyzed as specified in section 5.3.5.3 Initial Testing of the Non-Propellant Portion of Aerosol Coating ProductsThe non-propellant portion of the product sample is analyzed to determine the reactive organic compounds in the sample, including the presence of any prohibited compounds.This analysis is conducted by performing the following tests:35.3.1 Gravimetric analysis of samples to determine the weight percent of total volatilematerial, using US EPA Reference Methods 24/24A, ASTM D 2369-01.5.3.2 Determination of sample water content. For determination of water content eitherASTM D 4017-96a, or ASTM D 3792-99 may be used, or results from bothprocedures may be averaged and that value reported.5.3.3 Determination of ammonium content using ASTM D 1426-98 or US EPA Method300.7.5.3.4 Determination of ketones and alcohol content using NIOSH Method 1400.5.3.5 Analysis of reactive organic compounds and, if present, prohibited compounds (USEPA Reference Method 18, US EPA Method 8240B, US EPA Method 8260B, ASTMD 859-00, NIOSH Method 1400).5.4 Prohibited CompoundsIf the sample is found to contain compounds prohibited by the Aerosol Coatings Regulation (e.g., ozone-depleting compounds) at concentrations equal to or exceeding 0.1 percent by weight, the Executive Officer will reanalyze the sample for confirmation.5.5 Initial Determination and Verification of Reactive Organic Compound ContentThe Executive Officer will determine the reactive organic compound content by verifying formulation data pursuant to sections 5.2 and 5.3. Only those components with concentrations equal to or greater than 0.1 percent by weight will be reported.5.5.1 Based on manufacturers formulation data and the analysis conducted under section 5,the Executive Officer will make an initial determination of whether the product meetsthe applicable requirements specified in the Aerosol Coatings Regulation. If initialresults show that the product does not meet the applicable requirements, theExecutive Officer may perform additional testing to confirm the initial results.5.6 Final Determination of Reactive Organic Compound Content3Alternate test methods may be used, as provided in section 7.0If a product’s status is not satisfactorily resolved under section 5.1 - 5.5, the Executive Officer may conduct additional analyses and testing as necessary to verify the formulation data.5.6.1 If the Executive Officer is unable to verify the accuracy of the supplied formulationdata, then the Executive Officer will request the product manufacturer or responsibleparty to supply additional information to explain the discrepancy.5.6.2 If the additional information supplied by the manufacturer or responsible party showsthat the product does not meet the applicable requirements, then the Executive Officerwill take appropriate enforcement action.5.6.3 If the manufacturer or responsible party fails to provide additional information asspecified in section 5.6.1, the initial determination of reactive organic compoundcontent under section 5.1 – 5.5 shall determine if the product is in compliance withthe applicable reactive organic compound limits. This determination may be used toestablish a violation of the Aerosol Coatings Regulation.5.6.4 If there exists a discrepancy that cannot be resolved between the results of Method310 and the formulation data or additional information supplied by the manufactureror responsible party, then the results of Method 310 shall take precedence over thesupplied formulation data or additional information. The results of Method 310 shallthen determine if the product is in compliance with the applicable requirements, andmay be used to establish a violation of the Aerosol Coatings Regulation.6 METHOD PRECISION AND ACCURACY6.1 The precision of Method 310 for determining VOC content was evaluated using sevenrepresentative products with known volatile organic compound (VOC) contents ranging from 6.2 to 81.2 percent VOC by weight. Each sample was divided into six portions, and each portion was separately analyzed to determine the VOC content. Based on the results of this analysis, the 95 percent confidence interval for Method 310 is 3.0 percent by weight (Wt/Wt%).6.2 For determining the percent by weight of the individual ingredients in aerosol coatingproducts, the precision and accuracy of the determination for each ingredient is governed by the precision and accuracy of the test method used to ascertain the percent by weight of each ingredient.7 ALTERNATE TEST METHODSAlternative test methods which are shown to accurately determine the concentration of VOCs or constituent components in antiperspirant/deodorants, consumer products, or aerosolcoating products (or their emissions) may be used upon written approval of the Executive Officer.Method 310 - Appendix APROPELLANT COLLECTION PROCEDURES1 APPLICATIONThe procedure applies to modify ASTM D 3074-94 and D 3063-94 to allow collection of the propellant for analysis and density measurement for metal aerosol containers and glass aerosol containers, respectively. These modified procedures also retain the aerosol standard terminology listed in ASTM D 3064-97.2 LIMITATIONSNitrogen analysis: Nitrogen may be used as a component of the propellant system. Ambient air is 78 percent nitrogen and may be present as a contaminate in the system prior to sample collection. This is eliminated by sweeping out any connecting lines to the Tedlar bag with product before starting sample collection. This procedure will eliminate or reduce nitrogen contamination to less than 0.1% by weight of the sample and the analysis of the propellant gas will be unaffected.3 APPARATUS AND MATERIALS3.1 Propellant Collection System: See Figure 1 (metal containers) and Figure 3 (glasscontainers).3.2 Tedlar Bags equipped with slip valve and septum3.3 Density Measurement3.3.1 250 mL gas dilution bulb, or3.3.2 Density/Specific gravity meter meeting the following minimum specifications:3.3.2.1 Measurement Range: 0 – 3 +/- 0.00001 g/cm33.3.2.2 Measurement Temperature Range: 4o C ~ 70o C.3.4 Balance, capable of accurately weighing to 0.1 mgAppendix A: Method 310 Page 13.5 Sample Venting Platform.
