Abstract: Objective To establish a method for determining ketamine and its major metabolites in urine. Methods The ketamine and its major metabolites in urine was extracted with organic solvent and detected by GC/NPD, GC/ECD, GC/FID and GC/MS. Results The major metabolites of ketamine in urine were identified. The limit of detection was 2ng/mL for ketamine and 5ng/mL for norketamine, the limit of quantitation of ketamine and norketamine was 10ng/mL. Conclusion The method is shown to be applicable to detecting ketamine and its major metabolites in urine.
