一般描述

Chromolith® columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith® Performance RP-18 endcapped HPLC columns have macropores with 2 μm diameter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å) and the surface modification is octadecylsilane with full end-capping. Chromolith® Performance RP-18 endcapped columns fall under the USP L1 Classification. The column efficiency is comparable to a 5 μm particle size fully porous particulate column. Chromolith® Performance RP-18 endcapped columns are perfectly suitable for LC-MS applications. The column dimension of 100 mm length and 4.6 mm I.D. is the best choice for separations of complex samples 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 viscosity The recommended Guard-columns are: Chromolith® RP-18 endcapped 5-4.6 guard cartridges (3 pieces) [1.51452] with the Chromolith® Guard Cartridge Holder 5 mm x 4.6 mm [1.52032] Or Chromolith® RP-18 endcapped 10-4.6 guard cartridges (3 pieces) [1.51451] with the Chromolith® Guard Cartridge Holder 10 mm x 4.6 mm [1.52033] 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).
