近红外漫反射光谱法在毒品同一来源认定中的应用

Identification of drugs from different sources with clustering analysis by near infrared diffuse reflectance spectroscopy

目的:建立毒品同一来源认定的新方法。方法:应用近红外光谱积分球和光纤漫反射技术结合化学计量学方法进行处理,对不同途径缴获的毒品进行系统聚类分析。结果和结论:聚类分析技术对不同途径缴获毒品的来源进行了鉴别,该法简便、快速、准确,为毒品同一来源认定提供了一种新的方法。

Aim： To develop a new method for the identification of drug addicts from different＇sources. Methods： Near infrared diffuse reflectance technique in combination with clustering analysis was used to identify the drugs obtained from different sources. Results： It was found that the approach was capable of sorting out the source of the drugs. Conclusion： This established method is efficient, simple, reliable and non-destructive in the identification of drugs.
