APPLICABILITY: The working range is 0.00025 to 0.01 mg/m 3
for a 200-L air sample and 0.002 to 0.07 mg/m 3
for a 30-L air
sample. This method collects particulate arsenic only; if arsenic trioxide vapor is present, use the sampler in Method
7901. This is an elemental analysis, not compound specific. Volatile organic arsenic compounds, As 2O3
vapor, and arsine are
not collected efficiently by this sampling method
