Abstract:Objective: to determine the content of sulfate omeprazole magnesium in raw medicine established by ion chromatography. Methods:thermo IonPac AS19 (50mm×4mm)anion exchange column and IonPac AG19 (50mm×4mm)anion protective column, eluent:3.6mmol/L sodium carbonate and 6 mmol / L sodium bicarbonate solution and velocity: 1.0mL/min, the column temperature: 30℃, the conductance pool temperature: 35℃, anion suppressor current 40mA, sample volume: 25μL. Results: The linear range of Sulfate was 0.1~40.0μg/mL (r=0.9996), the recovery rate was 100.3%. Conclusion: the method is accurate and reliable, and can be used for determination of omeprazole magnesium sulphate impurity in raw medicine.
Keywords:Ion chromatography  Magnesium sulfate  Determination of Omeprazole
