SiELC Primesep S is a normal-phase HPLC column featuring embedded acidic ion-pairing groups. This column is available in all standard dimensions and comes with fully porous particles as well as 2.7 µm solid-core particles. Typical applications include the separation of common sugars and other neutral or extremely polar molecules. It can also retain and separate amino acids using different buffers at low concentrations.
