Application


  • 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).

General description

Chromolith® Performance 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® Performance RP-18 endcapped columns have macropores with 2 μm diameter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å), and the surface modification is octadecylsilane with full end-capping. Chromolith® Performance RP-18 endcapped columns fall under the USP L1 Classification. The column efficiency is comparable to a 5 μm particle size fully porous particulate column. Chromolith® Performance 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 separations of complex samples on any 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 5-4.6 guard cartridges (3 pieces) [1.51452] with the Chromolith® Guard Cartridge Holder 5 mm x 4.6 mm [1.52032] Or Chromolith® RP-18 endcapped 10-4.6 guard cartridges (3 pieces) [1.51451] with the Chromolith® Guard Cartridge Holder 10 mm x 4.6 mm [1.52033]. 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] Need more efficiency? Chromolith® High Resolution RP-18 endcapped 100-4.6 HPLC columns [1.52022] provide a column efficiency exceeding 140,000 plates/meter.
