AN72481: Trace Anions by Single Pass AutoNeutralization and Ion Chromatography (IC): DI Water Injection
Description
Trace anions determinations in caustic solutions require high dilution to minimize column overload by the caustic sample. However, the high dilutions required prevent analysis of trace anionic contaminants. Here a single pass approach to neutralize the base sample is demonstrated using both suppressors run in recycle mode. The run time was reduced from 45 min in the previous version of this application, AN 93 using “Park and AutoNeutralize” to 12 min. This application is demonstrated on a DI water sample to determine baseline contamination. An ICS-6000 can be used for this application.| Market: | Chemical |
