AN73267: Determination of Perchlorate in Drinking Water using Ion Chromatography
Instrument Type: IC
This application note updates the method with a high resolution IonPac AS16 4µm-2mm column. In comparison to the IonPac AS16 column, the IonPac AS16-4µm column exhibits higher peak efficiency while maintaining the same selectivity. This application note shows that using AS16-4µm column saves 3 min per injections, thereby improving productivity in perchlorate determinations in drinking water. Key performance parameters were evaluated including separation, linearity, limits of detection, accuracy, and precision. Perchlorate concentrations were determined in three drinking water samples.
