title: Separation of penicillin and its major degradation products by ion-pair reversed-phase high-pressure liquid chromatography.
abstract: An ion-pair reversed-phase high-pressure liquid chromatographic technique capable of separating penicillin and its major degradation products within 8 min was developed. The influence of pH, counterion concentration, buffer concentration, and organic modifier content was studied and the observed behavior of the compounds during the chromatographic process was discussed.
