Gas chromatography refers to chromatography using a gas as the mobile phase. At present, gas chromatography has been developed mainly from packed columns to capillary columns. The principle is to use gas (carrier gas) as the mobile phase, so that the sample is developed under the state of gas and separated in the chromatographic column made of appropriate stationary phase. Each component enters the detector successively and the concentration of the component is converted into electrical signals. After amplification was recorded, qualitative analysis was performed according to the retention time of each peak, and quantitative analysis was possible based on the size of the peak area or peak height.
Pesticide residue detectors have been widely used in modern development situations because the issue of food safety has always been a matter of concern to governments of all countries, and the standards developed have become increasingly stringent. China continues to increase the detection index of pesticide residues, and the standard value of the maximum limit of pesticide residues also gradually decreases. At present, the exchange of import and export trades has become increasingly frequent, and higher requirements have been placed on the detection capacity of food pesticide residues at entry ports. It is important to promote rapid, simple, and accurate detection methods. The introduction of new technologies and the optimization and improvement of traditional technologies are also pendulum. Only in this way can the major tasks of inspection and quarantine personnel at the port safeguard the quality and safety of food products, and provide strong technical support for the import and export of food products.

Detection of Pesticide Residues in Imported Food by Pesticide Residue Detectors
After pesticides are applied in agricultural production, some pesticides may be indirectly or directly left in crops. This is called pesticide residue. The port bears the task of inspection and quarantine for entry into the country and must ensure the safety of food imports. According to statistics, the application of insecticides in the United States can increase soybean production by 91%. It can be seen that the role of pesticides is beyond any doubt. However, because pesticides are a class of toxic chemicals, they are generally more difficult to degrade and are very likely to remain in food. They can endanger human health through enrichment, and it is crucial to scientifically detect pesticide residues in food. Some of the pesticides currently used can be biodegraded into harmless substances within a short time, but there are also some pesticides that are difficult to degrade and which are more persistent, such as: HCH, Endrin, methamidophos, organochlorine Wait. The problem of pesticide residues has caused serious harm to human survival and development. This article summarizes the research progress of pesticide residue detection technology in recent years, with a view to helping the technicians engaged in food pesticide residue detection. Pesticide residue detector is the most convenient instrument for pesticide residue detection in recent years, and the result is also very accurate.
