Method for identifying fentanyl drug components by terahertz

The invention relates to a method for identifying fentanyl drug components by terahertz. The method comprises the following steps: detecting a fentanyl standard sample by using terahertz waves to obtain a fentanyl terahertz intrinsic absorption peak position; transferring a to-be-detected sample to a polytetrafluoroethylene substrate, and shaking to dry the to-be-detected sample; a to-be-detected sample is detected by adopting a terahertz spectrometer device, and the to-be-detected sample is compared with the terahertz intrinsic absorption peak position of a standard sample, so that the to-be-detected sample is identified. According to the method, the fentanyl drug can be directly identified without opening cartons, luggage cases, clothes and other articles. 本发明涉及一种太赫兹对芬太尼毒品成分鉴定方法。该方法包括：以太赫兹波检测芬太尼标准样品，获得芬太尼太赫兹本征吸收峰位置；将待测样品转移至聚四氟乙烯基底上，晃动使其干燥；待测样品采用太赫兹光谱仪装置进行检测，与标准样品的太赫兹本征吸收峰位置进行比较，从而鉴定待测样品。该方法不需要打开纸箱、行李箱、衣服等物品，就可以直接对芬太尼毒品鉴定。
