Chlorate in Tap Water

A partial revision of the Japanese Water Quality Control Standards (Ministry of Health, Labour and Welfare Ordinance 135, Nov. 14, 2007), which added chlorate as a water control target item was implemented on April 1, 2008. It prescribes ion chromatography as the test method for chlorate. (Ministry of Health, Labour and Welfare Bulletin No. 386, Nov. 14, 2007)
This section introduces an example of the simultaneous analysis of chlorate and anions in tap water using a Shimadzu Prominence HIC-SP ion chromatograph and a Shim-pack IC-SA3 chlorate analysis column.

Ion Chromatograph

This separation/analysis instrument is widely used for the quantitative analysis of inorganic ions. Ion chromatographs are available as a suppressor type that allows ultra-high-sensitivity analysis to the ppb level and as a non-suppressor type that supports diverse applications.
