Neutral, Base, and Acid on Primesep 100 Column

Primesep 100 retains and separates an acid, base, and neutral in one HPLC injection. Maleic acid, benzylamine, and benzonitrile are resolved by ion-exclusion, ion-exhange and reversed-phase modes. The separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and trifluoracetic acid (TFA) with UV detection at 210 nm.
