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 Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately.
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.
TSKgel GMHHR-M Mixed Bed Columns are packed with rigid, multiple pore size, polymer beads. Mixed bed columns are commonly used for unknown samples and for the analysis of polymers with a broad molecular weight distribution.
TSKgel GMHHR-L Mixed Bed Columns are packed with rigid, multiple pore size, polymer beads. Mixed bed columns are commonly used for unknown samples and for the analysis of polymers with a broad molecular weight distribution.
TSKgel™ GMHhr-M Mixed Bed Columns are packed with rigid, multiple pore size, polymer beads. Mixed bed columns are commonly used for unknown samples, and for the analysis of polymers with a broad molecular weight distribution.
Ascentis™ Express PAH provides a stable, reversed-phase packing that can be used for analysis of acids, bases, and zwitterionic compounds, but has been specifically designed for the separation of polycyclic aromatic hydrocarbons.
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.
