General description
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), and 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.
The column dimension of 50 mm length and 2 mm I.D. is the best choice for fast and high-resolution separations meeting UHPLC and LC-MS needs.
Chromolith® 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® 2 mm I.D. columns truly unique. Chromolith® and Chromolith® 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 viscosity
The recommended Guard-columns are:
Chromolith® HighResolution RP-18 endcapped 5-2 guard cartridges (3 pieces) [1.52325] with the Chromolith® Guard Cartridge Holder 5 mm x 2 mm [1.52355]
