Descrição

Descrição geral

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

Chromolith^® Performance RP-18 endcapped 100-2 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^® Performance RP-18 endcapped 100-2 columns fall under the USP L1 Classification. The column efficiency is comparable to a 3-4 μm particle size fully porous particulate column. Chromolith^® Performance RP-18 endcapped 100-2 columns are perfectly suitable for LC-MS applications.
The column dimension of 100 mm length and 2 mm I.D. is the best choice for fast separations of complex samples on any U/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-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]

Aplicação

• Rapid Determination of 30 Polyphenols in Tongmai Formula: This study utilized the Chromolith^® RP-18 endcapped column in a liquid chromatography-tandem mass spectrometry setup to analyze 30 polyphenolic compounds in a traditional Chinese medicine formula, demonstrating its application in pharmaceutical analysis and quality control of complex herbal formulations (Wang et al., 2017).


• Ultra-fast gradient LC method for omeprazole analysis using a monolithic column: The Chromolith^® RP-18 endcapped column was employed in an ultra-fast gradient liquid chromatography method for the analysis of omeprazole in enteric-coated pellets, highlighting its efficiency in pharmaceutical quality control and rapid method development (Borges et al., 2010).
