AN201: Determination of Chloride and Sulfate Methanol Using Ion Chromatography

Instrument Type: IC

This application note presents a simple and direct approach for determining chloride and sulfate in methanol using a Reagent-Free™ IC system with eluent generation (RFIC-EG™ system). Chloride and sulfate are determined in less than 12 min using an IonPac® AS24 column with an electrolytically generated potassium hydroxide eluent and suppressed conductivity detection. The linearity, limits of quantitation, and precision of chloride and sulfate determination in methanol are demonstrated. This RFIC-EG system method delivers a fast and automated assay of chloride and sulfate in methanol.
