LC Chromatography Columns

Ligand on 100 Angstrom silica Thermo Scientific Betasil C18 Columns feature high surface area with high bonded phase coverage.

Columns designed to produce reliable, reproducible results for HPLC and UHPLC applications. Products operate in a variety of phases and are available with a range of stationary phases and column dimensions.

5µm particle size, 300 Angstrom pore size Proprietary, protein-friendly, ion exchange ligands of polyethyleneimine (PEI) bound to pure deactivated silica Low hydrophobicity Capacity of 0.22mEq/g 3% carbon load Use for normal phase and hydrophilic

Say goodbye to the limitations of traditional columns and experience greater speed, lasting durability and better results from your liquid chromatography instrument. Brownlee Superficially Porous Particle (SPP) columns produce sharper peaks and
