Hair drug trace on-site rapid detector

OneProduct background：

With the globalization and the accelerated development of society, China's drug crime is showing a high incidence and abuse trend. Relevant state departments attach great importance to the scientific research on drug control. Among them, improving drug detection technology has become an important part of anti-drug scientific research.

In order to solve the current public security anti-drug police on the drug-addicted personnel for urine, saliva testing means of various shortcomings, accurate service of drug-fighting, for practical combat, close to the needs of the actual work, the Ministry of Public Security issued the "drug-related personnel hair sample testing norms", put forward for drug-related personnel hair sample extraction, preservation, transmission and testing requirements. According to this request, our company developedTseng RDTD19H Hair Drug Trace Rapid Detector (Hair Drug AnalysisInstrument)。 At present, the product has been the Ministry of Public Security Safety and Police Electronic Product Quality Testing Center issued by the product inspection report, hair drug testing system has obtained software copyright, software products and provincial science and technology departments issued by the new report of science and technology.

Second, product advantages：

Hair has an incomparable advantage as a statutory biological test sample. Hair follicles are surrounded by dense capillaries, and drugs or drugs present in the blood enter the hair follicles of the scalp during hair growth, from the blood to the scalp, and are fixed by the protein in the hair, and about 3-5 days the haircontaining the drug grows out of the scalp surface. Hair grows outward at a relatively constant rate, and according to this mechanism, the type, time and dose of drug abuse can be inferred, which is what the "trace" test is all about.

Hair drug trace detection technology also has unique advantages include, detection time frame, drug or drug abuse information comprehensive, sample anti-corruption, easy to collect, easy to save, repeatable sampling and so on. Among them, the long detection time frame is the most prominent advantage, according to hair length can reflect a few weeks to months of drug use, up to 3 to 6 months of drug use history, combined with urine testing technology, can be more comprehensive evaluation of the drug abuse of the subject, to meet the needs of drug treatment work.

Third, the technical principle:

Quantum dots are a new type of fluorescent marker material, and quantum dots are made up of a limited number of atoms, all of which are in the nanoscale. Quantum dots are generally spherical or spherical, nanoparticles with a stable diameter of 2-20 nm made of semiconductor materials, and are one of the four nanomaterials most likely to be applied on a large scale in 2006. This quantum dot in semiconductor materials can lock electrons into a very small three-dimensional space, and when a beam of light is shining, electrons are excited to jump to higher energy levels. And when these electrons return to their original lower energy levels, they emit a beam of wavelength.

The Tongxing RDTD19H Hair Drug Detector (Hair Drug Analyzer) uses quantum dot method to quickly test illicit drugs based on a beam emitted by quantum dots.

V. Product Overview:

Tsing Xing RDTD19HHair drug trace rapid detector (Hair Drug AnalysisInstrument), using advanced quantum dot fluorescence technology, according to the beam emitted by the quantum dot, can easily generate in 10 minutes for hair morphine, crystal meth, ketamine (commonly known as K powder) three common drugs of rapid and accurate test results, with high signal-to-noise ratio, high resolution, high wavelength accuracy, rich test accessories and so on, The need for qualitative and quantitative analysis and scientific research on drug violations can be easily met in less than 10 minutes. At the same time, the results and values will be printed out, as the public security anti-drug police on-site inspection and disposal basis.

Six, product features and advantages:

● Advanced technology: Quantum dot fluorescence technology is a new and most accurate rapid testing technology of immunological method.

Fast detection: Quantitative testing of drug content in hair samples of suspicious people can be completed quickly in 10 minutes.

High sensitivity: a minimum detection of 0.2 ng/mg of drugs, in line with the anti-drug association's industry standards.

Easy sampling: a little hair can be (5mg), does not involve privacy, avoid adulteration of the adjustment package.

Easy to store: hair room temperature can be stored, and urine, blood and other materials generally need low-temperature frozen storage.

Long traceability: Hair can be used up to 3-6 months to detect the presence of suspected people with drugs.

Constant environment: the use of the thermostatic incubator, can effectively exclude the time, room temperature is too low and other factors on the reaction.

Quantitative precision: accurate sampling method, constant experimental process, guaranteed to obtain more reference quantitative test results

Easy to operate: simply train the inspectors for precise operation.

On-site testing: The necessary instruments, reagents and other accessories are all packed in the test case of about 20 inch suitcase.
