Dionex OnGuard II Ba/Ag/H Column

Dionex OnGuard II Ba/Ag/H is a three-layer column containing Dionex OnGuard II Ba, Ag, and H styrene sulfonic acid resin.

Ba resin removes high concentration sulfates from the sample matrix
Ag resin can easily remove chlorides, bromides, and iodides from concentrated matrices
●H
Resin exhibits high selectivity towards multivalent cations such as calcium and transition metals
Ideal choices for removing high concentrations of alkaline earth and transition metals, neutralizing alkaline samples, and removing carbonates from sample matrices

●

Three layer pillars can replace the series connection of three individual pillars, and also have the advantage of high silver capacity
