Dionex™ InGuard™ Na/HRP Cartridges

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 Thermo Scientific™ Dionex™ InGuard™ Na/HRP Cartridges. Installed in-line between the autosampler and IC injection valve, Dionex InGuard Na/HRP cartridges contain a blend of sulfonated resin in the sodium form and hydrophilic divinylbenzene resin to remove both organic contaminants and cations (including metals) from a sample for general purpose cleanup.
