Pre-packed columns, cartridges, and guard columns for separation of biomolecules and organic/inorganic analytes; includes normal/reversed phase HPLC, UHPLC, LC-MS, HILIC, mixed-mode, ion exchange, ligand exchange, and affinity column formats.
SUPELCOSIL™ LC-ABZ phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar.
Like their 5 micron siblings, 3 micron Zenix™ SEC columns feature a hydrophilic surface layer to prevent the sample from interacting with the underlying silica.
The bonded phase in Zenix™-C SEC columns is more polar than the hydrophilic phase used in Zenix™ columns, making Zenix™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
Ascentis™ Express Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.
A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent.
SUPELCOSIL™ LC-18-DB Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits.
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.
