HPLC Separation of Active Compounds in Drug Formulation
An HPLC method for the separation of active drug compounds on a Primesep 200 column. The retention of compounds is achieved through reverse-phase, cation exchange and hydrophobic interactions. Benzoic acid, hyoscyamine sulfate and phenyl salicylate are baseline separated using simple mobile phases of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) with a UV detector.
