IntroductionClause 47 of Annex XVII of the REACH Regulation regulates cement and cement - containing preparations for their water - soluble chromium (VI) content. It has the ob...
Brief method summary:A fixed volume of buffered and filtered sample, typically 100 mL, is injected into the eluant flow path and separated by anion exchange using an ammonium sulfate bas...
U.S. Geological Survey:Chromium (Cr) is usually present in surface and ground water in either the +3 or the +6 oxidation state. Because Cr(III) is considered an essential nutrient and Cr(VI) is consid...

Hexavalent chromium (Cr(VI)) compounds are a group of chemical substances that contain the metallic element chromium in its positive-6 valence (hexavalent) state. Occupational exposures to Cr(VI) occu...
The chromium (VI) is extracted from the filter using a carbonate/bicarbonate buffer solution and then analyzed by differential pulse polarography....
The general procedure for collection and analysis of air samples of Cr(VI) is described in OSHA method no. ID-103 (11.1.). Briefly, the Cr(VI) sample is collected on a 37-mm polyvinyl chloride (PVC) f...
1. Introduction This method can determine the amount of specific metal and metalloid particulates in the workplace atmosphere. The airborne particulates are collected on filters using calibrated s...
This method describes the collection and subsequent analysis of airborne metal and metalloid particulate by Inductively Coupled Argon Plasma-Atomic Emission Spectroscopy (ICAP-AES). 1.1.2 This method ...
