NIOSH 5003


This test method uses a HPLC (UV detection) technique to detect 1,1-dimethyl-4,4′-bipyridium cation. The paraquat cation is the analyte for this method; therefore, either salt, the dichloride or bismethyl sulfate, can be quantitated. This revises Method S294.

Analysis Type (Application Method): HPLC (UV detection)
