The determination of low ng/l sodium in the power industry is critical in identifying and preventing corrosive conditions in many power plant components. To address this challenge, we developed an ion chromatographic method to determine sodium at ng/

Ion chromatography with on-line matrix elimination reliably determines low microgram-per-litre amounts of magnesium and calcium in brine (30% NaCl). Magnesium and calcium from 100 μl of brine were concentrated on a metal-chelating resin containing i

Disinfection byproduct anions such as bromate, chlorite and chlorate pose significant health risks, even at low microgram/l levels in drinking water. A direct injection, ion chromatographic method was developed using a Dionex AS9-HC anion-exchange co
