Background
Since the end of the 90 s of the 20 th century, hair analysis has been increasingly used in forensic, clinical and anti-contrastive fields. Compared with traditional biological matrixes such as urine, blood and the like, the hair analysis has the outstanding advantages of noninvasive and simple sample collection, long toxic (drug) detection time window and the like. Therefore, the hair analysis result is often used as important evidence in case investigation to provide the case with reconnaissance direction and time information. The prior analysis method focuses on fragment analysis of the hair, and the length of 2-3 cm is used as interval segmentation. The traditional segmentation mode can only analyze the medicine taking condition in a period of time, and cannot obtain exact time information. Therefore, in practical work, there is an urgent need for a method of analyzing trace amounts of drugs in hair after a single intake of the drugs.
