Abstract

The invention discloses a chromogenic test colorimetric card for new psychiatric active substances and a design method thereof, and relates to the field of detection of the new psychiatric active substances. The colorimetric card provided by the invention integrates a color development result map obtained after multiple color development reagents react with multiple new psychoactive substances oneby one. The new psychoactive substances comprise 15 substances such as etizolam, flubrozepam, clozepam, fennazepam and the like. The chromogenic reagent comprises a formaldehyde-concentrated sulfuricacid reagent, an improved formaldehyde-concentrated sulfuric acid reagent, a 5% ferric sulfate reagent, a nitric acid sulfuric acid reagent, a gallic acid reagent, a Simmental reagent, a sodium nitroprusside reagent, a hydroxamic acid reagent, a vanillin reagent and a copper sulfate reagent. By means of the technical scheme, the 15 kinds of new psychoactive substances can be subjected to color development only by preparing the 10 kinds of color development reagents in advance and utilizing a test tube, a beaker, a glass slide, a white porcelain plate or a thick white paper plate, and a colordevelopment result is compared with a colorimetric card, so that criminal investigation technology inspectors can preliminarily screen suspicious new psychoactive substances on site.

Description

technical field [0001] The invention relates to the field of detection of new psychoactive substances, in particular to a color comparison card and a design method thereof for rapid on-site color detection of 15 common new psychoactive substances. Background technique [0002] New Psychoactive Substances (NPS), also known as "designer drugs" or "laboratory drugs", are drug analogues produced by lawbreakers by modifying the chemical structure of controlled drugs. It has similar ingredients to drug-controlled products, and even has stronger excitatory, hallucinogenic, and narcotic effects. In the real society, there are many new psychoactive substances in the form of tea bags, spices, bath salts, flavoring agents, etc., which are stored in paper bags, bottles, capsules, etc. Trading sales. At the same time, the abuse of new psychoactive substances will make the human body addictive, and cause chronic recurrent brain diseases, damage physical and mental health, and lead to va...
