Chromolith® HPLC Columns


Chromolith® HPLC columns provide excellent separations in a fraction of the time that a standard particulate column will take - typically four times faster, because they are made from highly porous monolithic rods of silica with a bimodal pore structure. The column is no longer packed with small particles but instead consists of a single piece of high-purity silica gel. Longer lifetime and lower matrix sensitivity with biological samples are additional advantages of Chromolith® columns. Multiple Chromolith® columns coupled together provide separation efficiencies of 100,000 plates/column at normal pressure.
