Primesep S is a normal-phase analytical column featuring embedded acidic ion-pairing groups. This column is available in all standard dimensions, and comes with fully porous particles as well as our 2.7 µm solid-core particles.

Key features of Primesep S include:

– It is highly suitable for the separation of common sugars and other neutral or extremely polar molecules.
– It retains and separates amino acids using different buffers at low concentrations.
– It separates weak bases via an ion-exchange mechanism.
– It separates acids using an ion-exclusion mechanism.

The mobile phases can be chosen for various chromatographic applications, such as LC-MS and preparative chromatography, and for low UV detection. The column operates within a working pH range of 1.0 to 4.5.
