Simplify complex applications while improving ion chromatography (IC) performance by automatically removing matrix interferences such as cations (including transition metals), anions, or hydrophobic substances with the Thermo Scientific™ Dionex™ InGuard H Cartridge. Installed in line between the autosampler and IC injection valve, this cartridge contains styrene-based, sulfonic acid resin in the hydronium form. Dionex InGuard H cartridges are ideal for sample pretreatment and removal of alkaline earth or transition metals, and can also be used for pH adjustment of basic samples.
