LC Guard Column Holders

Polymeric 100 &Aring columns for general reversed phase separations. pH stable from 1 to 13 Better sample recovery than silica-based columns (there are no silanol groups) Excellent durability (stable to any concentration of water or organic

Polymeric anion exchange packings for separation of inorganic and organic anions. Easily separate the eight common anions (fluoride through sulfate) Good separation of fluoride from the water dip Use with organic solvent from 0 to 100 % for elution

Guard columns can provide many benefits when used upstream from an analytical, preparative, or semi-preparative column. Guard columns are typically chosen to have the same packing as the primary column.

Hamilton chromatography resins can be ordered in bulk, i.e.
