Description générale

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]

Application


  • A Novel and Sensitive LC-MS/MS Method for the Quantitation of Ceftiofur in Pharmaceutical Preparations and Milk Samples.: This study, conducted by Levent et al., introduces a highly sensitive LC-MS/MS method for quantifying ceftiofur in pharmaceutical preparations and milk samples. The method utilizes Chromolith® HighResolution RP-18 endcapped columns, showcasing their application in enhancing the resolution and sensitivity of chromatographic analysis in complex matrices (Levent et al., 2021).

Folic acid or folate is classified as a B vitamin (B9). Folic acid is synthetically produced, and used in fortified foods and supplements. Folate is converted by humans to dihydrofolate (dihydrofolic acid), tetrahydrofolate (tetrahydrofolic acid), and other derivatives, which have various biological activities.

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).

Les petites molécules sont des ions ou des composés d'une masse moléculaire généralement inférieure à 900 daltons. Ces molécules peuvent être séparées efficacement et analysées par HPLC, UHPLC et LC-MS en utilisant essentiellement des particules de silice ou des phases stationnaires monolithiques présentant un large éventail de chimies de colonnes (modifications) différentes.
