Abstract:ISO 16740:2005 specifies an ion chromatographic method for the determination of the time-weighted average mass concentration of hexavalent chromium in workplace air and is applicable to the determination of masses of 0,01 micrograms to 10 micrograms of hexavalent chromium per sample, without dilution. For a nominal 1 cubic metre air sample, this equates to a measurement range of between approximately 0,01 micrograms per cubic metre to 10 micrograms per cubic metre, suitable for assessing exposures in plating o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
