Chromatofocusing of the drugs, containing paracetamol, on the reversed-phase sorbents

Abstract

The chromatofocusing technique was applied for linear and quasi-linear pH-gradient formation within the reversed-phase columns, packed with Diasorb D-130-C18и Diasorb-100-CN-mono for the first time. The optimal mobile phases are: the start buffer – 25 mM KH2PO4 + 25% CH3CN, pH 3,0, the eluent – 3,15 mM KH2PO4 + 25% CH3CN, pH 6,8-7,0. The chosen chromatographic conditions were used for separation of drugs “Maxicold” and “Efferalgan-C” by chromatofocusing technique on the sorbent Diasorb-100-CN-mono.
