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.
Ascentis™ Express HPLC columns, through the use of Fused-Core™ particle technology, can provide you with both the high speed and high efficiencies of sub-2 μm particles while maintaining lower back pressures.
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.
The Hamilton PRP-C18 HPLC column is designed to provide high-efficiency, reversed-phase separations over an extended column life in nearly any mobile phase or pH.
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.
LiChrosorb™ RP-18 HPLC Columns are classified as L1 USP columns and are primarily used for reversed-phase HPLC of neutral, acidic and weak basic compounds. The totally porous irregular particles ensure reliable results.
