Remove high levels of alkaline earth and transition metals from sample matrices and neutralize highly alkaline samples such as sodium hydroxide or sodium carbonate. Carbonate can then be removed by sparging the sample. The Thermo Scientific™ Dionex™ OnGuard™ II H Cartridge is an off-line sample preparation technique that eliminates these matrix interferences to improve ion chromatography (IC) performance and facilitate low-level ion analysis. Use them singly or in series, or pretreat up to 12 samples in parallel using the optional Thermo Scientific Dionex OnGuard Sample Prep Station.

Cartridges use a 16% cross-linked, styrene-based, sulfonic acid resin in the hydrogen form with high selectivity for multivalent cations such as calcium and transition metals.
Solve Tough Application Problems
- Boost sensitivity, lower baselines, and get better separations by removing phenolics, metals, cations, anions, hydrophobic substances, and more
- Achieve reproducible trace-level determinations in concentrated matrices
- Increase the lifetime of your analytical columns
- Use for a wide range of matrices thanks to wide pH stability
- Supports applications with choice of 1cc and 2.5cc formats, as well as syringe barrel format for robotic processing (custom order)
Easy-to-Use, Leak-Free
- Leak-free, no-channeling cartridge
- Quick, secure Luer inlet connections
- Ships with a Certificate of Analysis that verifies capacity, performance and cleanliness
- Use the optional Dionex OnGuard Sample Prep Station and OnGuard Sample Pretreatment Cartridges
