Industrial Chromatography

Simplify complex applications while improving ion chromatography (IC) performance by automatically removing matrix interferences such as cations (including transition metals), anions, or hydrophobic substances using Thermo Scientific™ Dionex™ InGuard™ Ag Cartridges. Installed in line between the autosampler and IC injection valve, Dionex InGuard Ag Cartridges use a styrene-based sulfonic acid resin in the silver form for sample pretreatment and removal of chloride, bromide, and iodide from concentrated sample matrices such as brines.

The Dionex InGuard Ag Cartridge resin is the same material used in Dionex InGuard II Ag cartridges. When using a Dionex InGuard Ag Cartridge, a Dionex InGuard H or Dionex InGuard Na cartridge should be placed after the Dionex InGuard Ag cartridge to remove any residual silver ions.
