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 Therm Scientific™ Dionex™ InGuard™ Na Cartridges. Installed in line between the autosampler and IC injection valve, Dionex InGuard Na Cartridges contain styrene-based, sulfonic acid resin in the sodium form and are ideal for removal of alkaline earth or transition metals without acidifying the sample.
This Dionex InGuard Na Cartridge attribute ensures good recovery of acid-labile analytes such as nitrite. This resin is designed to have very high selectivity for multivalent cations such as calcium, magnesium, and transition metals.
