Abstract: A reversed phase ion-pair liquid chromatographic method using a base deactivated column and pulsed electrochemical detection on a gold electrode is described. It allows the separation of a mixture of spectinomycin sulfate, lincomycin hydrochloride and their related substances. A step gradient was necessary to obtain a good separation together with a reasonable analysis time of 40 min. The mobile phases consisted of an aqueous solution of 3.3 or 0.55 g/l pentanesulfonic acid, 10 mM acetic acid and 20 ml/l tetrahydrofuran. Both mobile phases were adjusted to pH 4.0 with diluted sodium hydroxide. The influence of the different chromatographic parameters on the separation was investigated. Two commercial samples were analyzed using the described method. In total 12 components could be separated.
