General description

All Chromolith® columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith 4.6 mm columns have macropores with 2 µm diamter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å), the surface modification is octadecylsilan with full end-capping.
