Industrial Chromatography

Remove chloride, bromide, and iodide, trap silver and other cations, neutralize caustic sample and remove carbonate. Eliminating these sample matrix interferences using this off-line sample preparation technique improves performance of ion chromatography (IC) and facilitates trace analysis. The Thermo Scientific™ Dionex™ OnGuard™ II Ag/H Cartridge layers the resins from both Dionex OnGuard II Ag and OnGuard II H cartridges and provides greater silver capacity. Use them singly or in series, or pretreat up to 12 samples in parallel using the optional Thermo Scientific™ Dionex™ OnGuard™ Sample Prep Station.
