In recent years, there have been five major advances in the field of pesticide residue analysis including the detection technology of rapid detection instruments for pesticide residues.
1) Near-infrared spectroscopy technology, which is a new type and portable near-infrared spectroscopy technology developed rapidly in recent years. Its research and application provide a broad approach for the detection of pesticide residues;
2) Three-dimensional fluorescence technology, stoichiometry-fluorescence spectroscopy, etc. have also been applied to the determination of pesticide residues;
3) In recent years, some instrument companies have introduced a pesticide residue tester with higher separation efficiency and faster analysis speed. Therefore, the technology is highly praised, but due to high prices, domestic popularity is still a long time.
4) In the 1990s, the full-destination gas chromatography was introduced, which has attracted people's attention due to its advantages such as high efficiency, high resolution, and higher reliability.
In a word, in the past 20 years, the research progress of the detection technology of pesticide residue rapid measurement instruments is very obvious, the main direction is the miniaturization, portable, and multi-technology combination of detection instruments. Among the numerous detection technologies, the most widely used one is the detection technology of pesticide residue fastness tester, which has good detection sensitivity, accuracy, precision, and relatively low price, and will be the pillar technology of pesticide residue analysis in China.
Research progress of detection technology of pesticide residue rapid tester
With the development of other disciplines at the same time, more and more new technologies have been applied to the detection and analysis of pesticide residues, such as the application of rapid detection instruments for pesticide residues. In the increasingly perfect pesticide residue detection method, the use of more residue detection technology and rapid screening of detection technology, combined with various advanced pretreatment tests, each with its own characteristics has become the current in pesticide residue detection of agricultural products. The development of the mainstream, forming a simple, fast, sensitive, low-cost, easy to promote the direction of development.
