This method is for the collection and analysis of elements (metals). The sample is collected on a 0.8 micron cellulose ester membrane. The filter is digested using concentrated hydrochloric acid (HCl) and concentrated nitric acid (HNO3), and after digestion the sample is analyzed using ICP (inductively coupled plasma).
The working range of this method is up to 100 mg/m³ for each element in a 500L air sample.
NOTE: This method is similar to NIOSH Method 7301 differing only in the use of the hot block for the digestions of the sampler.

* 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.
