Amphetamine tablet homogenization method

Abstract

The invention discloses an amphetamine tablet homogenization method which comprises the following steps: homogenization treatment is performed on an amphetamine tablet by utilizing a household stirrer; the household stirrer comprises a stirrer main body as well as a dry grinding cup and a dry grinding cutter base matched with the main body, and the dry grinding cutter base is matched with the main body of the stirrer; the amphetamine tablet is put into the dry grinding cup. The invention further provides a homogenization effect evaluation method. Quality control and evaluation are implemented from two aspects, that is, particle sizes of crushed sample granules, and relative standard deviation of contents of target substances in samples taken in different positions, thus being scientific and reasonable. The invention further establishes a method for washing the household stirrer for the amphetamine tablet, and provides parameters and a calculation method for evaluating a washing effect. Experiment shows that by adopting the methods, amphetamine drug tablet inspection requirements of international standard methods for quantitative and qualitative international standard methylamphetamine drug detection, industrial methods for MDMA (methylene dioxymetham-phetamine) drug detection can be met, a good washing effect can be achieved, and the methods are reliable.

Description

technical field [0001] The invention relates to a method for homogenizing amphetamine tablets. Background technique [0002] The qualitative and quantitative identification of drugs plays an important role in the investigation and litigation of drug cases, and is an important basis for the court to convict and sentence criminal suspects. The "Regulations on Several Issues Concerning the Examination and Judgment of Evidence in the Handling of Death Penalty Cases" and the "Regulations on Several Issues Concerning the Exclusion of Illegal Evidence in the Handling of Criminal Cases" were promulgated and implemented on July 1, 2010. Regulation. [0003] Seized drugs are the most critical physical evidence in drug cases, especially for cases with a large amount of drug trafficking and a large number of packages, how to carry out laboratory tests on seized drug samples in a representative, legal and standardized manner has become a concern in the investigation and litigation proce...

AI Technical Summary

Problems solved by technology

So far, my country has not formulated a corresponding homogenization standard method to standardize the sampling process. In practice, manual grinding with a mortar and bowl is the main method, which is highly random and poorly controllable, which reduces the accuracy and repeatability of drug testing.

Especially for amphetamine-type drug tablets, due to the poor production conditions and poor workmanship of underground processing plants, the distribution of active ingredients is very poor, and it is especially necessary to carry out artificial homogenization treatment to ensure the effectiveness of the sampling and testing process

[0004] The sampling of drugs is closely related to and inseparable from the inspection and identification work. It is far from being able to meet the needs of the current drug case investigation and litigation by only positioning the drug inspection and identification work on the qualitative and quantitative inspection of drug components. It is necessary to expand the research field to standardize drug testing. In the pre-processing process, innovate and standardize the homogenization method to ensure the reliability and effectiveness of physical evidence, thereby ensuring the reliability of drug case identification conclusions
