AN1145: Determination of Halogens in Coal Using Combustion Ion Chromatography

Instrument Type: IC

When coal is burned, the exhaust contains halogens that can be released into the atmosphere as acid gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF), which can harm vegetation, animals, and infrastructure directly or cause acid rain. In this application note, coal samples were combusted in the Mitsubishi AQF-2100H system and then fluorine and chlorine were accurately and precisely determined using the Dionex ICS-2100 Ion Chromatography System with a Dionex IonPac AS15 anion-exchange column set.
