- W2357147356 abstract "Objective:To establish the high-performance liquid chromatography tandem mass spectrometry(HPLC-MS/MS) with high sensitivity and lower detection for the determination of barbiturates [barbital(bar),phenobarbital(phe),amobarbital(amo) and secobarbital(sec)] in urine.Methods: The human urine was processed by liquid-liquid extraction(LLE),concentrated by nitrogen and analyzed by HP LC-MS/MS.Results: 4 kinds of barbiturates in urine showed good linearity in the concentration range of 0.01 mg/L~0.2 mg/L and the linear correlation coefficient was over 0.99.The recovery was between 91.3% and 106.8%.The detection limit of bar was 0.005 mg/L.The limit of detection of phe,amo and sec were all 0.002 mg/L.Conclusion: This method can be used for determination of barbital in human urine with wide linear range,short analytical time and low detection limit." @default.
