摘　　要：目的　考查了N甲基双三氟乙酰胺 (MBTFA)衍生化试剂对苯丙胺类毒品的衍生化效果与衍生化条件 ,建立该类毒品三氟乙酰化后的定性定量分析条件。方法　用三氟乙酰化气一质联用分析方法。结果　获得了衍生化产物经气质联用分析后的总离子流色谱图、质谱图及质谱断裂规律 ,以及各种定量参数。结论　经三氟乙酰化后分离效果得到改善 ,且衍生化完全 ,可用于该类毒品的定量分析。Objective To examine the derivatization results and conditions of MBTFA derivative reagent to Amphetamines. Method The derivation of MBTFA were analyzed by GC/MS, ResultQualitative and quantitative analysis conditions to this kind of drugs after tri-fluorine acetylation were set up. Conclusion The regulation to the products and some quantitative parameters after derivatization by GC-MS were determined.
