Thermo Fisher Scientific Inc. has announced that 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.
