This method is for the collection and analysis of elements (metals). The sample is collected on a 0.8 micron cellulose ester membrane or 5 micron PVC (polyvinyl chloride) membrane filter. The filter is digested using HNO3/HClO4, and after digestion the sample is analyzed using ICP (inductively coupled plasma).
The working range of this method is 0.005 to 2.0 mg/m³ for each element in a 500L air sample.
NOTE: This method replaces Method P&CAM 351 for trace elements.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
