Portable drug field identification equipment and method

Abstract

The invention relates to portable drug field identification equipment and method. The equipment comprises a control module, a rectangular ion trap mass spectrome analysis module, a data collection andprocessing module, a spectrogram recognition and warning module and a result output module, wherein a drug test specimen or a practical sample generates current signals after passing through identification equipment; the current signals are converted into voltage signals; an inside clock outputs time signals; voltage signals are converted into digital signals; time signals and digital signals areextracted; normalization and base line correction processing are performed; if a sample is a drug standard sample, a standard spectrum base is generated; if the sample is a practical sample, a samplespectrogram is generated; the sample spectrogram and the standard spectrum base are subjected to feature comparison. The equipment and the method have the advantages that the size is small; the weight is light; complicated pre-treatment is not needed; liquid samples or solid samples are directly subjected to feeding sample detection; the automatic recognition, warning and printing on the detection result can be realized; the single sample detection and warning time is shorter than 2s; the equipment and the method are suitable for drug field investigation and seizing and identification; wide application prospects are realized.

Description

technical field [0001] The invention relates to the field of on-site drug detection equipment, in particular to a portable on-site drug identification device and method. Background technique [0002] Drugs have become a big cancer that endangers society. Drug crimes not only endanger personal life and health, but also endanger public safety. The focus of my country's anti-drug work during the "Twelfth Five-Year Plan" period is "blocking the source and intercepting the flow", but the drugs seized by inspection equipment each year account for only 4%, which is far from meeting the needs of the anti-drug struggle. Equipment for the detection, evidence collection and identification of toxic chemicals is imperative. [0003] At present, the main drug detection technologies include X-ray technology, biotechnology, chromatography-mass spectrometry, capillary electrophoresis, neutron and Raman technology, and ion mobility spectrometry. Although these technologies are playing a role...

Problems solved by technology

Although these technologies are playing a role in my country's anti-drug work, each technology has its own defects, such as X-ray technology, whose instruments are bulky and can only be used in specific occasions such as airports and railway stations; biotechnology such as Anti-drug dogs, its stability and reliability are poor; neutron and Raman technology instruments are more expensive, and the cost of use is high.
