AU200: Fast Anion Determinations in Environmental Waters Using a High-Pressure Compact Ion Chromatography System

Instrument Type: IC

The determination of anions is one of the most important IC applications. Here we have updated Application Note 154 with the 4µm-resin-particle IonPac AS18-Fast-4µm column with expected backpressures approaching the previous system's limitations. In this Application Update, fast anion runs (9 min) were achieved with a gradient separation, saving 4 min run time with while retaining similar chromatography with higher sensitivity than the previous application. This analysis was facilitated by the high pressure capable Dionex Integrion HPIC system configured for Reagent-Free IC.
