Abstract: | A method for the determination of sulbactam in milk by reversed phase high performance liquid chromatography(HPLC) internal standard method was established. Chromatographic conditions: Shimadzu C18 column(4.6mm × 250 mm id, 5 μm), column temperature: 30 ° C, mobile phase: acetonitrilephosphate buffer = 8: 92, pH 5.0(V/V) : 1m L/min, detection wavelength of 210 nm. And the linear correlation coefficient was 0.9996 and the internal standard working curve method was quantitatively determined in the range of 1.004 ~ 20.08mg/L. The results showed that the average recovery of sulbactam was 97.3%(RSD = 0.41%). Conclusion: This method is simple, rapid, accurate and accurate, and has been applied to the detection of actual samples |
