Pesticide residue analysis is the use of pesticide residue detector and other instrument analysis methods for trace analysis of pesticide residues in food, usually including sample preparation and testing in two parts. Sample preparation is the core. In the aspect of sample preparation, the development trend of modern chromatographic sample preparation technology is to make the process of processing the sample simple, the processing speed is fast, the use device is small, the introduced error is small, the selectivity to the component to be measured and the recovery rate To be high.
The study of pesticide residue detector technology should be rational, scientific, and objective to the problem of pesticide residues in food, because the detection of pesticide residues is a very technical work, it involves assessment criteria, sampling points and sample size, pesticide species, and vegetable varieties. And analysis comes from many aspects, such as quality control directly affects the scientific and authenticity of the test results.
The scope of pesticide residues in the sample range of recovered pesticide species, the recovery rate is also higher in the application of pesticide residue detector technology, not only for oil purification effect, and good reproducibility, and analysis of the pillars can be reused, has become a universal Purified pesticide residue analysis method. In general, the purpose and result of the development of pretreatment technology is to achieve rapid, efficient and simple completion of sample preparation and automated analysis processes.
