Primesep 100 is a mixed-mode analytical column with acidic ion-pairing groups embedded into long hydrophobic ligand chains. Primesep 100 columns are available in all standard dimensions, with 10, 5, 3 µm fully porous particles, and 2.7 µm solid-core particles.

This column is the most versatile in the entire Primesep family for separating a broad range of compounds.

– Enhances retention of basic compounds through cation-exchange mechanism.
– Separates acids by ion-exclusion mechanism.
– Retains neutral compounds by reverse-phase mechanism.
– Offers mobile phases suitable for LC-MS and preparative chromatography, as well as low UV detection.
