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.
TSKgel™ CM-2SW columns are packed with 5 micron, high efficiency, spherical silica beads which are surface modified with a weak cation exchanger. They are used for the separation and analysis of small proteins, peptides, and other biologically active molecules. They have a smaller pore size than the TSKgel™ CM-3SW columns.
Packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in different solvent systems. Used for the separation of polymers that are soluble in polar organic solvents. Exclusion Limit (DMF): Polyethylene Oxide 400,000 Da.
apHera™ reversed columns were devoloped specifically to provide the superior advantages of both silica and polystyrene columns, without the disadvantages of either.

Have analytes with medium hydrophobicity or need a less hydrophobic phase to obtain optimum retention? These columns provide outstanding sensitivity and excellent peak shape.
TSKgel Phenyl-5PW RP offers similiar selectivity to its hydrophobic interation counterpart TSKgel Phenyl-5PW, although a higher degree of cross-linking allows for increased stability in aqueous/organic mobile phase gradients. Provides an advantage over silica when high pH buffer systems are needed.
TSKgel ODS-80Tm is a general purpose column for the analysis of low MW pharmaceuticals, bases, nucleosides and nucleotides. Common applications include purity checks and peptide mapping.
The most hydrophobic among the three TSKgel™ HIC columns, TSKgel™ Phenyl-5PW is an excellent choice to screen for the selectivity, retention and recovery of most biomolecules.
TSKgel™ SuperHZM-N Mixed-Bed Columns are packed with rigid, porous, polymer beads each having a varying mean pore diameter. They are used for the analysis of organic-soluble polymers with high molecular weights of less than 700,000 Da.
Chromolith™ High Resolution 2 mm I.D. 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 octadecylsilan with full end-capping.
