Descrizione

Descrizione generale

Chromolith^® columns are made of monolithic silica with a characteristic bimodal pore structure.

Chromolith^® Performance RP-8 endcapped columns have macropores with 2 μm diameter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å), the surface modification is Octylsilane with full end-capping. Chromolith^® Performance RP-8 endcapped columns fall under the USP L7 Classification. The column efficiency is comparable to a 5 μm particle size fully porous particulate column. Chromolith^® Performance RP-8 endcapped columns are suitable for LC-MS applications.
The column dimension of 100 mm length and 4.6 mm I.D. is the best choice for fast 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-8 endcapped 5-4.6 guard cartridges (3 pieces) [1.52013] 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). [1.51467]
