Dionex OnGuard II Ag Cartridge has a similar resin to and is often used in concert with the Thermo Scientific™ Dionex™ OnGuard™ II H cartridge, which removes dissolved silver and other cations. Use the Dionex OnGuard II Ag Cartridge before using the Dionex™ OnGuard II H cartridge. Also consider the Thermo Scientific™ Dionex™ OnGuard™ II Ag/H cartridge.

Solve Tough Application Problems

• Boost sensitivity, lower baselines, and get better separations

• 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

Performance Guaranteed

• Ships with a Certificate of Analysis that verifies capacity, performance and cleanliness

Pretreat 12 Samples Simultaneously

• Use the optional Dionex OnGuard Sample Prep Station and OnGuard Sample Pretreatment Cartridges

Remove chloride, bromide, and iodide from sample matrices to improve performance of ion chromatography (IC) and facilitate trace analyses. Performed prior to IC analysis, the Thermo Scientific™ Dionex™ OnGuard™ II Ag Cartridge is an off-line sample preparation technique that eliminates these matrix interferences using a silver-form, high-capacity, suffocated, cation-exchange resin. Pretreat a single sample or many samples in series. Use them singly or in series, or pretreat up to 12 samples in parallel using the optional Thermo Scientific™ Dionex™ OnGuard™ Sample Prep Station.
