| 摘 要： | 采用气相色谱一傅立叶变换红外光谱联用技术,建立了9种苯丙胺类毒品及其衍生物的分析鉴别方法.采用HP-1(30 m×0.32 mm,0.25 μm)毛细管柱,MCT红外检测器与氢火焰检测器同时检测,在程序升温条件下,以十七烷为内标物,研究已知对照品的色谱保留行为及其气态红外光谱图特征,建立相应的特征吸收峰数据库,作为鉴别分析的依据.色谱保留时间与红外特征吸收峰联合鉴别法极大地提高了鉴别的准确性.将发展的方法应用于可疑毒品物证中苯丙胺类及其衍生物毒品样品的鉴别,获得了理想的结果.本方法可用于涉毒案件毒品物证的检验,特别适用于混合毒品成分的检验.

| Abstract: | Gas chromatography-infrared spectroscopy technique has been used for the quantitative analysis of amphetamine-type stimulants.Capillary column of HP-1(30 m×0.32 mm,0.25 μm) was coupled with MCT infrared spectroscopy and flame ionization detecters using temperature programming for identification of nine ampletamine-type stimulants.Chromatographic retention behaviors were studied using heptadecane as internal standard for separation and identification of the stimulants.On another hand,infrared spectra of the gaseous amphetamine-type stimulants were measured using chemical reference substances of the stimulants and the characteristic peaks from the collected spectra were supplied as an assistant identification.The cooperation of information from retention time and infrared spectrum should improve the reliability of the method.The analysis of real samples showed satisfactory results.The method could be applied to the stimulant identification,especially to that of complicated sample. |
