Problems solved by technology

In this case, if only the method for a single drug is used for analysis, it is easy to cause missed detection. Therefore, in practice, there is an urgent need for a screening analysis method for multiple types of drugs and their metabolites in hair.

Embodiment 1

[0079] A police station sent his hair for inspection, and the suspect claimed that he had never touched drugs. The hair sent for inspection is analyzed by the method of the present invention, not only methamphetamine and its metabolite amphetamine are detected in its scalp 0-3cm section, but also MDMA and its metabolite MDA are detected simultaneously, and the specific detection results are shown in figure 1 .

Embodiment 2

[0081] A police station submitted hair for inspection, and the suspect admitted to skating "ice"; the hair submitted for inspection was analyzed by the method described in the present invention, not only methamphetamine and its metabolite amphetamine were detected, but also ketamine and its metabolite to Methylketamine; It can be seen that the application of the method of the present invention can simultaneously screen multiple alkaline drugs to reduce the risk of missed detection. For the detection results of this embodiment, see figure 2 .

Embodiment 3

[0083] A police station submitted hair for inspection, and the suspect admitted to skating "ice"; the hair submitted for inspection was analyzed by the method described in the present invention, not only MDMA and its metabolite MDA, but also ketamine and its metabolite norketamine were detected. Cocaine and its metabolite benzoylecgonine; it can be seen that the method of the present invention can be used to screen a variety of alkaline drugs at the same time to reduce the risk of missed detection. For the detection results of this embodiment, see image 3 .

Abstract

The invention belongs to the technical field of poison detection, and particularly relates to a method for simultaneously detecting 12 kinds of basic poisons in hair. The method for simultaneously analyzing 12 kinds of psychoactive drugs in hair has the advantages of simplicity, convenience, high speed and wide analysis range. Compared with the existing method, the method has the advantages that the liquid-liquid extraction process is omitted in aspects of sample pretreatment; the whole process can be completed in 1h; no increase time exists; oppositely, during the analysis of a plurality of samples, the high flux advantages are shown. By using the technical scheme provided by the invention, the external pollution detection and instant quantitative analysis of the practical cases can be realized; the positive case data accumulation is convenient. Therefore the method for simultaneously detecting 12 kinds of basic poisons in hair has excellent selectivity, linear relevancy, precision and accuracy; meanwhile, LOD and LOQ are sufficiently low, so that the poison sources can be successfully presumed; the technical support can be provided for correct distinguishing of illegal abuse andclinic medication; the considerable market potentials are realized.

Description

technical field [0001] The invention belongs to the technical field of drug detection, in particular to a method for simultaneously detecting 12 basic drugs in hair. Background technique [0002] As we all know, basic drugs represented by morphine, codeine, methamphetamine, and amphetamine are the most widespread and most harmful in my country. [0003] Compared with other biological samples such as blood and urine, hair samples have the advantages of easy acquisition, easy storage, stable target objects, and a long detection time limit. In particular, hair samples can reflect for a long time (months or years) ), therefore, it plays an important role in the identification of forensic drug ingestion, and has become the evidence of drug addiction identification in our country. [0004] In addition, in judicial identification, the detection of drug components in human hair samples has been added as scientific evidence for identifying drug addicts; however, there is still a lac...
