Remove inorganic anions and strong organic acids contaminants from sample matrices and neutralize highly acidic samples to improve ion chromatography (IC) performance and facilitate trace ion analysis. Performed prior to IC analysis, the Thermo Scientific™ Dionex™ OnGuard™ II A Cartridges are an off-line sample preparation technique that eliminates these matrix interferences using styrene-based, anion-exchange resin in the bicarbonate. Use them singly or in series, or pretreat up to 12 samples in parallel using the optional Dionex OnGuard Sample Prep Station.
