- W2365861024 abstract "OBJECTIVETo establish two methods for determining the ketamin by TLC and GC-MS. METHODSThe specimens were alkalized and extracted with ethyl acetate. In GC-MS analysis the DB-5MS quartz capillary column with Electron Impact source(EI) were used for ketamin determination using SKF(525A )as a internal standard. Qualitative analysis can be condncted for morphine, Heroin and ketamin by the combined R(f) of drugs spots and the TLC spectrum scaning chart. RESULTSBy TLC method,ketamin, morphine and heroin had a good separation. In the GC-MS analysis, the linear range was (0.5)-(20.0) mg·L~( 1) (r=(0.998 7)). The detective limit was (0.2) mg·L~( 1) (S/N=3). CONCLUSIONThe TLC and GC-MS methods can be used to detect ketamin from drugs and for the forensic medical identification of ketamin abuse." @default.
