Phenyl Hydride HPLC Columns for stability and precision Click to enlarge

Cogent Diamond Hydride™HPLC columns

Excellent for Extreme Polarity  |  Slightly Hydrophobic   |   TYPE-C™ Silica

These useful HPLC columns have a silica hydride surface similar to other TYPE-C™ phases but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to a small but important level.


Popular choice of scientists working in metabolomics or bioanalytical with LCMS for compounds such as amino acids, organic acids, carbohydrates and very polar small molecules. Precise methods are easily developed even with complex sample matrices including biological fluids such as plasma, urine, saliva and other bio matrices.
