ISO Releases New Standard for the Determination of Bromate
Nov 25 2011
Thermo Fisher Scientific announce its bromate analysis solutions are fully compliant with the new ISO standard for bromate analysis by ion chromatography (IC) titled, Water quality — Determination of dissolved bromate — Method using ion chromatography (IC) and post column reaction (PCR) (ISO 11206:2011(E)). The standard adds improved limits of detection and simplifies the lab work compared to ISO 15061:2001.
Bromate, generated by the ozonation of bromide during water disinfection has been listed by the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) as a potential carcinogen at the low μg/L level. In Europe, the Council Directive 98/83/EC (DWD) on the quality of water intended for human consumption lists bromate with a maximum allowed limit of 10 μg/L.
Dionex analytical IC solutions, now sold under the Thermo Scientific brand, allow for the determination of both standard anions (F-, Cl-, NO2-, Br-, NO3-, PO43-, SO42-), e.g. as major components at ppm levels, and the trace determination of bromate at ppb or sub-ppb levels.
