Abstract:Objective: To detect Chlordiazepoxide in urine by dispersive liquid-liquid micro-extraction and gas chromatography mass spectrometry. Methods: Chlordiazepoxide in urine was extracted with chloroform and methanol at pH8 and was analyzed by GC-MS, its content was determined with internal standard curve. Results: The detection limit of the Chlordiazepoxide in urine was 0.002μ g/ml, and the standard curve was linear in the range of 0.01 -2 μ g/ml. The average recovery of Chlordiazepoxide was 89.8% (RSD = 3.86%, n = 5 ). Conclusion: This method is simple, high sensitivity and suitable for quick analysis of the Chlordiazepoxide in urine.
Keywords:Chlordiazepoxide  dispersive liquid-liquid micro-extraction  gas chromatography mass spectrometry  urine
