Abstract

The present invention relates to a drug extraction kit, extraction method and detection method in hair. The extraction kit includes a composite extraction solution, and the composite extraction solution contains a disulfide bond reducing agent, a hydrogen bond blocker, a hair expander and Solvent, the composite extract is alkaline, and the pH is 8.5-10. The drug extraction kit in hair uses the reduction method to hydrolyze the hair, no special crushing equipment and extraction equipment are required for pretreatment, the hydrolysis time is short, and the entire extraction process is simple to operate. Compared with the traditional acid method, alkali method, methanol solvent method and buffered salt solution Methods such as the enzymatic method and the enzymatic method are more suitable for the rapid detection of laboratory forensic identification. Further, the reagents used in the composite extract in the extraction kit are all water-soluble reagents, which are easy to extract liquid-liquid with organic reagents, so that the solution to be tested can be quickly separated, and the reagents used are basically non-polluting to the environment and non-toxic to operators. Easy to remove without residue, basically no damage to equipment.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to a drug extraction kit in hair, an extraction method and a detection method. Background technique [0002] Qualitative detection of drugs in hair is a detection technology emerging in the subject of forensic poison identification, mainly for the qualitative detection of opioids, amphetamines, ketamine and other drugs. Due to the advantages of easy preservation, stable compounds, and long monitoring time in hair, hair drug testing has been used for identification of drug addiction history. [0003] There are three main ways for the drug to enter the hair: (1) the drug is transported to the hair follicle through the blood circulation, and combines with it in the process of forming the hair medulla and cortex; (2) in the process of forming the hair shaft through the sweat gland and sebaceous gland. Equal secretion into the hair; (3) In the process of hair shaft formation, it ...
