Golubitskii, A. Ivanov, E. Basova, V. Ivanov] A procedure was developed for the rapid analysis of a new multicomponent anticatarrhal medication Maksikold by high-performance liquid chromatography (HPLC). The possibility of the simultaneous determination of all active substances in the preparation, including ascorbic acid, is an advantage of the proposed procedure. For the efficient resolution of the peaks of analytes and interfering additives, a mobile phase with the pH varied in the course of an experimental run was used. The procedure was used to analyze pilot samples of the preparation. The results obtained exhibit a high precision. Pleiades Publishing, Ltd., 2007 Golubitskii G.
