AN73852: Determination of Trace Anions in High Purity Waters using a Large-Volume Direct Injection Be the first to rate this application


This work describes the use of Dionex IonPac AS28-Fast-4μm column that was designed specifically for the trace analysis of inorganic anions and monovalent organic acids. Improved peak efficiencies in combination with the smaller column inner diameter result in lower detection limits compared to the Dionex IonPac AS15-5μm column. The analytes are detected by suppressed conductivity with a Dionex ADRS™ 600 suppressor. This application note expands on work presented in Application Update 142, “Improved determination of trace anions in high purity waters by high-volume direct injection
