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.
Use as a robust, general-purpose column for QC/QA applications. They are high-quality, base-deactivated, fully endcapped, have similar C18 selectivity but slightly less retentive.
Ascentis™ Express 90 Å Biphenyl columns can be used for basic, acidic, or neutral compounds with alternate selectivity from C18 and is especially useful for separating peaks that elute early on C18 and other phenyl phases.
TSKgel Alpha-M Columns are so-called mixed-bed columns with an extended linear calibration range. They are packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in different solvent systems.
Ascentis™ Express RP-Amide can be used for basic, acidic, or neutral compounds with orthogonal selectivity from C18 or C8. The polar-embedded Ascentis™ Express 5 μm RP-Amide columns are compatible with 100% aqueous mobile phases without suffering from 'phase collapse'.
Analytical teams that support biologic drug development require rapid, sensitive, and precise methods for protein quantitation from cell culture, fermentations broths, or purification intermediates.
The bonded phase in SRT™-C SEC columns is more polar than the hydrophilic phase used in SRT™ columns, making SRT™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
