Inductively coupled plasma atomic emission spectrometry and inductively coupled plasma MS are the major analytical tools for trace elements in environmental matrices, however, the underestimate of certain trace elements in analysis of air particulate matter by these two techniques has long been observed. This has been attributed to incomplete sample digestion. Here, we demonstrate that the combined effects of sample digestion, air filter impurities, and post‐adsorption of the analytes contribute to the interference of the analysis. Particular attention should be paid to post‐adsorption of analytes onto air filters after acid digestion. |
