Pesticides are inevitably used in agricultural production. This has certain toxic and side effects on humans and animals, and is extremely destructive to the environment and the biological chain. The problem of pesticide residues on fruits and vegetables is also a long-standing problem. . This has become an important factor in the development of China's fruit and vegetable industry, so it is of great significance to improve the quality and safety of fruits and vegetables and promote the development of the fruit and vegetable industry. Pesticide residue detectors are very common in modern applications and are also very effective testing instruments.
China's pesticide residue detection technology started late, and the commonly used residue detection methods are mostly traditional analysis methods. The solvent extraction method used in this method is time-consuming, laborious, and easy to pollute the environment; the sensitivity of the detection method is low, the extraction and purification efficiency is low, etc., it is difficult to adapt to the current analysis of pesticide residues, and can not meet the international limit requirements, especially the demand for export inspection; The wide application range, simple pre-processing, high efficiency and sensitive method greatly increase the workload and analysis time, which brings great difficulties to the detection of large quantities of samples.
Pesticide residue detection technology is moving toward rapid, efficient, multi-residue detection, automation and online analysis. However, due to high cost or immature technology, some new technologies will take time to formally promote and apply. The application of pesticide residue detector is also more recommended. With the further development and application of ultra-high-efficiency pesticides and the rapid increase in the number of sample detection, higher requirements are put forward for the sensitivity, specificity and rapidity of pesticide residue analysis and detection technology. It has also promoted the development and introduction of some new and advanced pesticide residue analysis technologies. These high-tech applications have greatly improved the qualitative ability of pesticide residue detection and the sensitivity and detection of detection, thus expanding the scope of detection coverage.
