标准范围
This International Standard specifies a procedure for the use of quadrupole inductively coupled plasma massspectrometry (ICP-MS) for analysing test solutions prepared from samples of airborne particulate mattercollected as specified in ISO 15202-1. Method development, performance checks, and a routine analysismethod are specified.Test solutions for analysis by this International Standard are prepared as specified in ISO 15202-2.This International Standard is applicable to the assessment of workplace exposure to metals and metalloidsfor comparison with limit values (see e.g. EN 689, ASTM E1370).The following is a non-exclusive list of metals and metalloids for which limit values have been set (seeReference) and for which one or more of the sample preparation methods specified in ISO 15202-2 andthe analytical procedure described in this International Standard are applicable. However, there is noinformation available on the effectiveness of any of these sample preparation methods for those elementslisted in italics.This International Standard is not applicable to determination of elemental mercury, since mercury vapour isnot collected using the sampling method specified in ISO 15202-1.The procedure is suitable for assessment of exposure against the long-term exposure limits for most of themetals and metalloids listed above when sampling at a typical flow rate of 2 l min?1 for sampling times in therange 0,5 h to 8 h and for assessment of exposure against the short-term exposure limits, where applicable.The procedure is subject to no significant spectral interferences (see A.3), provided that suitable analyticalisotopes are used. However, inadequate matrix-matching can adversely affect results.
