Abstract

The invention discloses a color comparison card for color detection of new psychoactive substances and a design method thereof, and relates to the detection field of new psychoactive substances. The color comparison card of the present invention is a collection of color development result diagrams of various color reagents reacting with multiple new psychoactive substances one by one. New psychoactive substances include 15 substances including etizolam, flubromazepam, dicloazepam, and fenazepam. Chromogenic reagents include Mahal's reagent, modified Mahal's reagent, 5% ferric sulfate reagent, nitric acid-sulfuric acid reagent, gallic acid reagent, Simon's reagent, sodium nitroprusside reagent, hydroxamic acid reagent, vanillin reagent and copper sulfate reagent. Just prepare the above 10 kinds of color reagents in advance, use test tubes, beakers, glass slides, white porcelain plates or thick white cardboards to develop colors for 15 new psychoactive substances, and compare the color results with the color comparison card Yes, it is conducive to the preliminary screening of suspected new psychoactive substances on-site by criminal investigation technical inspectors.

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...
