This cartridge is ideal for the removal of high levels of alkaline earth and transition metals from sample matrices, neutralization of caustic samples, and removal of carbonate.
  • The Ba resin removes high concentrations of sulfate from sample matrices
  • The Ag form easily removes chloride, bromide, and iodide from concentrated matrices
  • The H form is highly selective for polyvalent cations such as calcium and transition metals
This three-layer cartridge can be used in place of three single cartridges in series and has the added advantage of higher silver capacity

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 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
