All Chromolith® columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith® 25mm columns have macropores with 3 µm diameter, giving a column efficiency exceeding 50,000 plates/meter. The mesopores are 13 nm (130 Å), the surface modification is octadecylsilan with full end-capping.
Based on high-purity silica, Chromolith® Si is designed for normal-phase separations of polar non-ionic organic compounds. The column offers all of the benefits of monolithic silica technology.
