General Description

The Chromolith^®HighResolution RP-18 endcapped 100-4.6 HPLC columns Validation Kit consists of 3 columns from 3 different manufacturing batches.

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 100 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 viscosity

The 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). [1.51467]
