Embodiment 1

[0069] figure 1 A schematic diagram of the functional framework of the drug scene identification device is given. It can be seen from the figure that the instrument includes: control module I, rectangular ion trap mass spectrometry module II, data acquisition and processing module III, spectrum identification and alarm module IV and result output module V.

Embodiment 2

[0071] figure 2 A schematic diagram of the equipment structure of the on-the-spot drug identification device is given. like figure 2 As shown, preferably, the overall layout of the instrument is developed around the vacuum system. The structure layout of the instrument is divided into upper and lower layers, the lower layer is the vacuum pump system 9 and cooling fan 10, the upper layer is mainly embedded industrial computer 1, sample injector 5, ionization chamber 6, discontinuous atmospheric pressure interface 7 and vacuum chamber 8; power supply The power supply board 11 is located at the lower left side of the instrument, placed vertically, the mass spectrometer control board and the high-voltage power supply board 3 are stacked together and located at the front side of the instrument, placed vertically; the RF amplifier is hung on the outer wall of the vacuum chamber by screws, and is located at the right rear side of the instrument ; The printer 12 is fixed on the in...

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...
