NIOSH 7604


This test method uses ion chromatography and conductivity detection techniques to monitor Chromium Hexavalent. This method is less sensitive than method 7600 (colorimetric), but it contains fewer sample preparation steps and was found free from interferences when used for samples of five chromate-containing paints. This method is an alternative to NIOSH Method 7600 (colorimetric). All sample preparation should be performed in a hood.

Analysis Type (Application Method): Ion chromatography, conductivity detection
