Columns and cartridges for gas, ion, HPLC, low-pressure LC, and flash chromatography; includes pre-packed and open columns, packing, guard columns and accessories, and other supplies for flash chromatography.
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
The LC-SCX cation-exchange columns have strongly acidic propylsulfonic acid groups and are used for separating cations. Adjust pH, ionic strength, and organic modifier concentration to control retention and selectivity.
Well suited for the separation of neutral, acidic and weak basic compounds. MilliporeSigma LiChrospher™ 60 RP-select B LiChroCART™ HPLC Cartridge, 250-4 features a reliable and versatile traditionally produced spherical silica gel carrier that
An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.
Available in a variety of stationary phases that function in normal and/or reverse phase. MilliporeSigma™ LiChroCART™ HPLC Cartridge, 250-10 comes with customized packing (please specify packing material) and is 250mmL x 10mmI.D.
The Ascentis™ Express 2 μm OH5 stationary phase is a highly polar ligand that possesses 5 hydroxyl groups tethered to the silica via novel proprietary linkage chemistry.
