标准范围
本文件规定了许多合适的方法，用于从使用ISO 15202中规定的方法收集的空气中颗粒物样品中制备测试溶液？1、用于后续ICP法测定金属和类金属？使用ISO 15202中规定的方法进行AES？3.它载有关于测量已设定限值的金属和准金属的方法的适用性的信息。这些方法也可用于一些金属和准金属的测量，这些金属和准金属尚未设定极限值，但在这种情况下没有提供关于其适用性的信息。注:本文件中描述的样品制备方法通常适用于ICP以外的分析技术？AES，例如ISO 8518[5]和ISO 11174[10]的原子吸收光谱法（AAS）和电感耦合等离子体质谱法（ICP？MS）通过ISO 30011[11]。附录B中规定的方法适用于与可溶性金属或准金属化合物的限值进行比较的测量。当进行测量以与总金属和准金属及其化合物的限值进行比较时，附录C至H中规定的一种或多种样品溶出方法适用。关于个别方法适用性的信息在规定该方法的附件的范围内给出。以下是已设定限值（参见参考文献[14]和[15]）且本文件中规定的一种或多种样品溶出方法适用的金属和准金属的非排他性列表。然而，没有关于任何指定样品溶出方法对这些斜体元素的有效性的信息。铝钙镁硒钨锑铬锰银铀砷钴水星钠钒钡铜钼锶钇铍铪镍钽锌铋铟磷碲锆硼铁铂金铊铯铅钾锡镉锂铑钛ISO 15202不适用于元素汞或三氧化二砷的测定，因为汞蒸气和三氧化二砷蒸气不是使用ISO 15202中规定的取样方法收集的？1.
This document specifies a number of suitable methods for preparing test solutions from samples of airborne particulate matter collected using the method specified in ISO 15202？1, for subsequent determination of metals and metalloids by ICP？AES using the method specified in ISO 15202？3. It contains information about the applicability of the methods with respect to the measurement of metals and metalloids for which limit values have been set. The methods can also be used in the measurement of some metals and metalloids for which limit values have not been set but no information about its applicability is provided in this case.NOTE The sample preparation methods described in this document are generally suitable for use with analytical techniques other than ICP？AES, e.g. atomic absorption spectrometry (AAS) by ISO 8518[5] and ISO 11174[10] and inductively coupled plasma mass spectrometry (ICP？MS) by ISO 30011[11].The method specified in Annex B is applicable when making measurements for comparison with limit values for soluble metal or metalloid compounds.One or more of the sample dissolution methods specified in Annexes C through H are applicable when making measurements for comparison with limit values for total metals and metalloids and their compounds. Information on the applicability of individual methods is given in the scope of the annex in which the method is specified.The following is a non-exclusive list of metals and metalloids for which limit values have been set (see References [14] and [15]) and for which one or more of the sample dissolution methods specified in this document are applicable. However, there is no information available on the effectiveness of any of the specified sample dissolution methods for those elements in italics.AluminiumCalciumMagnesiumSeleniumTungstenAntimonyChromiumManganeseSilverUraniumArsenicCobaltMercurySodiumVanadiumBariumCopperMolybdenumStrontiumYttriumBerylliumHafniumNickelTantalumZincBismuthIndiumPhosphorusTelluriumZirconiumBoronIronPlatinumThalliumCaesiumLeadPotassiumTinCadmiumLithiumRhodiumTitaniumISO 15202 is not applicable to the determination of elemental mercury or arsenic trioxide, since mercury vapour and arsenic trioxide vapour are not collected using the sampling method specified in ISO 15202？1.
