Description générale

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

Chromolith® FastGradient RP-18 endcapped 50-2 columns have macropores with 1.5 μm diameter, giving a column efficiency exceeding 100,000 plates/meter. The mesopores are 13 nm (130 Å), the surface modification is octadecylsilane with full end-capping. Chromolith® FastGradient RP-18 endcapped 50-2 columns fall under the USP L1 Classification. The column efficiency is comparable to a 3-4 μm particle size fully porous particulate column. Chromolith® FastGradient RP-18 endcapped 50-2 columns are perfectly suitable for LC-MS applications.
The column dimension of 50 mm length and 2 mm I.D. is the best choice for fast separations on any U/HPLC System.

The revolutionary, monolithic silica with its unique combination of macropores and mesopores enable:
  • 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 5-2 guard cartridges (3 pieces) [1.52009] with the Chromolith® Guard Cartridge Holder (kit) 5 mm x 2 mm [1.52004].

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].

Chromolith® HPLC and UHPLC columns are made from monolithic silica with a bimodal pore structure using sol-gel technology.

Monolithic silica HPLC columns enable high-throughput analysis at low back pressure without loss of separation efficiency or peak capacity.

Contenu apparenté

Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
