Golubitskii, E. Basova, V. Ivanov] A procedure is developed for determining impurities in Validol tablets by gas-liquid chromatography (GLC). The reliability of the results obtained is confirmed by the analysis of model mixtures containing the active and all auxiliary substances of the tablets. The proposed procedure is introduced into the standardized documentation on the manufactured tablets. The presence of impurities in Validol tablets due to the technology of the synthesis of the Validol is inevitable. Therefore, the routine control of production is very important to ensure its quality. Pleiades Publishing, Ltd., 2007 Golubitskii G.
