Chromolith(R) columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith(R) HighResolution RP-18 endcapped columns have macropores with 1.15 mum 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(R) HighResolution RP-18 endcapped columns fall under the USP L1 Classification. The column efficiency is comparable to a 2.7 to 3 mum particle size fully porous particulate column. The column dimension of 25 mm length and 2 mm I.D. is the best choice for very rapid separations meeting UHPLC and LC-MS needs. Chromolith(R) HighResolution RP-18 endcapped columns with 2 mm internal diameter are ideal for use with UHPLC or UPLC instruments, thanks to their very small internal volumes. A particular benefit is very fast analysis, reduced sample-preparation and the low column backpressure. Ultra-high performance and extremely low operating pressure make Chromolith(R) 2 mm I.D. columns truly unique. Chromolith(R) and Chromolith(R) HighResolution columns are perfectly suitable for LC-MS use, however, the column dimension of 2 mm I.D. or below is preferred to be used in LC-MS methods.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(R) HighResolution RP-18 endcapped 5-2 guard cartridges (3 pieces) [1.52325] with the Chromolith(R) Guard Cartridge Holder 5 mm x 2 mm [1.52355]Learn more:Brochure: Race through your Separations on Any System.
