AN157: Comparison of Suppressed to Nonsuppressed Conductivity Detection for the Determination of Common Inorganic Cations

Instrument Type: IC

This application compares suppressed to nonsuppressed conductivity detection for the determination of inorganic cations. The Thermo Scientific Dionex IonPac CS16 was used to demonstrate the capabilities of a suppressed cation system, in terms of capacity, linearity, detection limits, and typical baseline noise using a self-regenerating suppressor. A silica-based cation-exchange column, the Thermo Scientific Dionex IonPac SCS 1, was evaluated for nonsuppressed cations and the results were compared to the suppressed system.
