General description

Chromolith^® columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith^® HighResolution RP-18 endcapped columns have macropores with 1.15 µm diameter, giving a column efficiency exceeding 140,000 plates/meter. The mesopores are 15 nm (150 Å), the surface modification is octadecylsilane with full end-capping. Chromolith^® HighResolution RP-18 endcapped columns fall under the USP L1 Classification. The column efficiency is comparable to a 2.7 to 3 µm particle size fully porous particulate column. Chromolith^® HighResolution RP-18 endcapped columns are perfectly suitable for LC-MS applications.The column dimension of 150 mm length and 4.6 mm I.D. is the best choice for high-resolution separations of complex compound mixtures on any HPLC System.The revolutionary, monolithic silica with its unique combination of macropores and mesopores enables:—Rapid separations at very low column back-pressure—High matrix tolerance, allowing time and cost savings with simplified workflows—Cost-savings due to extended column lifetimes—Connection of columns, flow gradients and the use of mobile phases with higher viscosityThe recommended Guard-columns are: Chromolith^® HighResolution RP-18 endcapped 5-4.6 guard cartridges (3 pieces) [1.52025]with the Chromolith^® Guard Cartridge Holder 5 mm x 4.6 mm [1.52032]The Chromolith^® column coupler can be used to significantly increase the separation efficiency of Chromolith^® columns by coupling several columns in series (up to 100,000 plates/per column).
