NIOSH 7303


This test method uses inductively coupled argon plasma and atomic emission spectroscopy techniques to monitor various metals. The analysis is not compound specific. Certain elemental compounds are known to be acceptable or unacceptable by this method. For unverified compounds, a test run should be conducted using a known amount of the compound in question to determine acceptability. Alternative, more sensitive methods exist for some elements by graphite furnace atomic absorption spectroscopy. This method is similar to NIOSH Method 7301, differing only in the use of the hot block for digestion of the sampler.

Analysis Type (Application Method): Inductively coupled argon plasma, atomic emission spectroscopy (ICP-AES)
