Workplace air - Determination of metals and metalloids in airborne particulate matter by inductively coupled plasma atomic emission spectrometry - Part 2: Sample preparation
1.1 This part of ISO 15202 specifies a number of alternative 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.
NOTE The sample preparation methods described in this part of ISO 15202 are generally suitable for use with analytical techniques other than ICP-AES, e.g. atomic absorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS).
1.2 The method specified in annex B is applicable when making measurements for comparison with limit values for soluble metal or metalloid compounds.
1.3 One or more of the sample dissolution methods specified in annexes C through G 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.
