NIOSH 6013


This test method uses an ion chromatography and conductivity technique to monitor sulfate ions. Some lots of charcoal have excessively high sulfur backgroun ds and/or poor desorption efficiencies; therefore, screening of each lot should be done before field use. Alternate methods are S4 which uses impinger collection, and P&CAM 296 which uses a molecular sieve sampler but has poor stability. Take precaution and all work should be performed in a fume hood.

Analysis Type (Application Method): HPLC-UV
