Problems solved by technology

Although the spectroscopic method is non-destructive testing, it is limited by each spectrum; the latter methods belong to destructive testing and are not suitable for application in the field of anti-narcotics
Commonly used in customs are X-ray scanning, trace detection, police dog identification, etc. These methods also have limitations: X-ray energy is high, penetrating power is strong, only the general outline can be distinguished but the type cannot be determined; for trace detection and police dog identification , only limited to traces of drugs remaining on the outside of the package

Embodiment 1

[0025] Example 1, taking morphine as an example.

[0026] In the first step, a standard sample of morphine is prepared, 30 mg of morphine and 120 mg of polyethylene are weighed, and the morphine is ground and mixed with polyethylene powder uniformly, and the mass ratio is controlled at 1:4. A round sheet with a diameter of 1.3 cm and a thickness of about 1.2 mm was formed on a tablet press with a pressure of 4 tons. The second step is to experimentally measure and build a map library. The samples were placed on a rotating sample holder, filled with nitrogen for about 2 hours to drive out the air in the device, and then measured using terahertz time-domain spectroscopy. The test environment is in a nitrogen atmosphere at room temperature, the air humidity range is 4%, and the frequency range of the terahertz absorption spectrum of anesthetics is 0.3-2.0THz. The time-domain spectrum is converted into the frequency-domain spectrum by Fourier transform, and then the terahertz ab...

Embodiment 2

[0027] Example 2, the narcotic drug is thebaine.

[0028] Similarly, a standard sample of thebaine was first prepared, 30 mg of thebaine and 60 mg of polyethylene were weighed, thebaine was ground and mixed with polyethylene powder uniformly, and the mass ratio was controlled at 1:2. The pressure is used to make a circular sheet with a diameter of 1.3cm and a thickness of about 0.8mm. The thebaine sample was placed on a rotating sample holder and filled with nitrogen for about 2 hours. The measurement was carried out using terahertz time-domain spectroscopy under a nitrogen atmosphere at room temperature and an air humidity range of 40%. The time-domain spectrum is converted into frequency-domain spectrum by Fourier transform, and then the terahertz absorption spectrum of thebaine in the frequency range of 0.3-2.0THz is obtained by using the data processing program. image 3 Shown is the terahertz fingerprint of a standard sample of thebaine. from image 3 It can be known t...

Embodiment 3

[0029] Example 3, the narcotic drug is papaverine hydrochloride.

[0030] Similarly, first prepare a standard sample of papaverine hydrochloride, weigh 30 mg papaverine hydrochloride and 240 mg polyethylene, and evenly mix the papaverine hydrochloride with polyethylene powder after grinding, and the mass ratio is controlled at 1:8. The pressure is made into a circular sheet with a diameter of 1.3cm and a thickness of about 1.8mm. The papaverine hydrochloride sample was placed on a rotating sample holder and filled with nitrogen for about 2 hours. Under a nitrogen atmosphere at room temperature, the air humidity range was 20%, and the measurement was performed by terahertz time-domain spectroscopy. The time-domain spectrum is converted into frequency-domain spectrum by Fourier transform, and the terahertz absorption spectrum of papaverine hydrochloride in the frequency range of 0.3-2.0THz is obtained by data processing program. Figure 4 Shown is the terahertz fingerprint of a...

Abstract

The invention discloses a method for detecting an anesthetic medicament by a standard fingerprint map established by applying terahertz waves, which comprises the following steps: preparing a standard sample of the anesthetic medicament, wherein the anesthetic medicament is any one of morphine, thebaine, papaverine hydrochloride, cocaine hydrochloride, and meperidine hydrochloride; detecting the standard sample of the anesthetic medicament by applying a terahertz spectrum device and establishing a standard fingerprint map library; and detecting an unknown sample by using the established standard fingerprint map library. The kind of drugs in packing materials can be accurately judged through the terahertz technology. The terahertz is used for detecting the drugs without damaging human bodies, materials and drugs. Therefore, non-destructive testing can be realized.

Description

technical field [0001] The invention relates to a method for detecting narcotic drugs, in particular to a method for detecting narcotic drugs by using terahertz waves to construct a standard fingerprint. Background technique [0002] According to Article 357 of the Criminal Law of the People's Republic of China, drugs refer to opium, heroin, methamphetamine (ice), morphine, marijuana, cocaine, and other narcotic drugs and psychotropic substances controlled by the state that can cause addiction. [0003] At present, the methods for identifying the type and content of drugs mainly include: spectroscopy (including infrared spectroscopy, Raman spectroscopy, X-ray, mass spectrometry, etc.), chromatography, capillary electrophoresis, etc. Although spectrometry is non-destructive testing, it is limited by each spectrum; the latter methods belong to non-destructive testing and are not suitable for application in the field of anti-drug. Commonly used in customs are X-ray scanning, t...
