NIOSH 6009 (Issue 2)

Mercury

This test method uses atomic absorption and cold vapor to monitor elemental mercury (quicksilver). For this method, the sorbent material irreversibly collects elemental mercury. A prefilter can be used to exclude particulate mercury species from the sample. The prefilter can be analyzed by similar methodology. The method has been used in numerous field surveys. This replaces method 6000 and its predecessors, which required a specialized desorption apparatus. Mercury is readily absorbed by inhalation and contact with the skin. Operate the mercury system in a hood, or bubble vented mercury through a mercury scrubber.

Analysis Type (Application Method): Cold Vapor Atomic Absorption (CVAAS)

Compatible Filters:

A 37 mm, cellulose ester membrane filter in a cassette preceding the sorbent may be used if particulate mercury is to be determined separately. Forceps to handle filter membrane.
