Workplace air. Determination of hexavalent chromium in airborne particulate matter. Method by ion chromatography and spectrophotometric measurement using diphenyl carbazide Ingestion-build-224916 contents of command-response pairs exchanged1 Scope This International Standard specifies a method for the determination of the time weighted average mass concentration of hexavalent chromium in workplace air. Separate sample preparation methods are specified for the extraction of soluble and insoluble hexavalent chromium. The method for insoluble hexavalent chromium can also be used to prepare samples for determination of total hexavalent chromium, if desired. This International Standard is
