| titleOfInvention | Method for determining omeprazole impurity components |
| abstract | FIELD: medicine. n SUBSTANCE: invention refers to medicine, mainly to pharmacology and pharmaceutical chemistry, and can be used for determining the admixture components of omeprazole. Disclosed is a method of determining the amount of impurities in reversed-phase high-performance liquid chromatography. Method consists in sample preparation consisting in sample dissolution with subsequent chromatography. Analysis is carried out using a chromatographic column with octodecylsilica gel (C18) and a mobile phase consisting of acetonitrile-isopropanol-water of deionised-orthophosphoric acid in ratio of components (35:15:45:5). Detection is carried out in amperometric detection conditions using a glass-carbon sensor with an operating voltage of 0.85 V. Chromatogram is recorded for 15 minutes. n EFFECT: method provides higher accuracy and rapidness of analysis when determining omeprazole impurity components. n 1 cl, 1 tbl, 1 ex |
