EcoChem Traditional Chinese Medicine Traceability Analysis System

EcoChemTraditional Chinese Medicine Traceability Analysis System

The quality, origin tracing, and authenticity discrimination of traditional Chinese medicinal materials are of great significance. However, conventional analysis methods such as UV spectrophotometry, atomic absorption spectroscopy, inductively coupled plasma mass spectrometry, etc. have many drawbacks, such as complex sample preparation, slow analysis speed, or inability to simultaneously analyze multiple elements. In recent years, based on laser-induced breakdown spectroscopy technology（LIBS）The laser spectroscopic elemental analysis system has attracted the attention of chemical analysis researchers due to its simple sample processing, fast analysis speed, and simultaneous analysis of multiple elements. Moreover, the obtained sample spectra can be used as fingerprint spectra for sample identification. This technology can provide cutting-edge detection methods for quality identification of traditional Chinese medicinal materials, rapid classification and identification, authenticity judgment of drugs, determination of harmful elements in drugs and packaging exceeding standards, and evaluation of medicinal plant germplasm resources and quality.

EcoChemThe traceability analysis system for traditional Chinese medicinal materials adoptsLIBSTechnology, detection limit can reachppmGrade. The measured elements can cover most of the elements in the periodic table, up to100varied. The solid-state laser of the system generates laser and acts on the surface of the sample. When the laser energy is greater than the breakdown threshold energy of the sample, plasma is formed on the surface of the sample. The sample materials excited by laser energy in these plasmas reach high-energy states and rapidly migrate back to low-energy states, emitting emission spectra with information about the types and contents of sample elements. These emission spectral signals are collected by an intelligent signal collection system and transmitted to a spectrometer for spectral analysis, and then detected by a spectral signal detector to obtain elemental information. This system has been applied in many fields such as element measurement and identification of traditional Chinese medicine, detection of soil and plant samples, detection of heavy metal pollution, mineral analysis, gemstone identification, etc.

At present, the production areas of traditional Chinese medicinal materials in China are approximately100Multiple, commercialized medicinal herbs approximately1200It is of great significance to trace the origin of traditional Chinese medicinal materials.

At present, there are still some problems with the existing technology, which makes it even more urgent to seek a new analytical method: in-situ, fast, and accurate.LIBSThe emergence of technology * this gap.
