This method is fast and cheap, but it has low specificity for pesticides and can only detect more than 30 kinds of pesticides. There are more and more types of pesticides and more complex brands. The Raman spectroscopy and mass spectrometry phone database screening methods introduced next are new technologies that replace biochemical methods. Raman spectroscopy uses a Raman scattero meter for detection, which has the advantage of being fast, but the disadvantage is that the false positives are high, and the specificity is not as good as that of the mass spectrometry quick screening method. As for the mass spectrometry quick screening method, it is a patented method developed by the Agricultural Drug Toxic Test Institute of the Agricultural Committee, and has obtained patents in many countries such as the European Union, the United States, Japan, and Taiwan. It is also a test method publicly recommended by the Food and Drug Administration of the Ministry of Health and Welfare . As long as each pesticide has a corresponding organic sensor, it can be detected, and the detection time of a single sample is as long as 10 minutes. More importantly, the inspection results are more accurate and correct, and it is the benchmark technology for pesticide inspection in the world. However, relatively, the cost of the instrument is very high, long-term investment is required, and the professionalism of the inspector is required. Taking medical applications in the era of epidemic prevention as an example, Raman spectroscopy is a good rapid screening reagent, while mass spectrometry screening is a PCR test with high accuracy and sensitivity.
