NIOSH 7900

ARSENIC and compounds, as As (except AsH3 and As2O3)

This method uses atomic absorption and flame arsine generation, to perform elemental analysis, not compound specific. Volatile organic arsenic compounds, As 2O3 vapor, and arsine are not collected efficiently by this sampling method. Note special precaution to perform all perchloric acid digestions in a perchloric acid fume hood. Method 7901 uses a sampler designed to collect As 2O3 vapor and an alternate measurement technique (graphite furnace-AAS). Method 7300 (ICP-AES) also gives an alternate measurement technique.

Analysis Type (Application Method): Atomic absorption, graphite furnace
