Abstract: Objective: To analyze the impurities produced by forced degradation of omeprazole sodium bicarbonate dry suspension. Methods: Silica gel column is bonded with octyl by LC-MS method. Results: By LC-MS spectrum analysis, 5 impurities are produced of omeprazole sodium bicarbonate. Conclusion: This method can infer the structure and source of the impurities in the sample.
Keywords: omeprazole sodium bicarbonate; LC-MS; impurity analysis
