OnGuard II Ba/Ag/H Cartridge

The OnGuard® II Ba/Ag/H is a layered cartridge containing OnGuard II Ba, Ag, and H styrene-based, sulfonic acid resins. 

  • 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 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. This three-layer cartridge can be used in place of three single cartridges in series and has the added advantage of higher silver capacity.
