Shimadzu develops new instruments for pesticide residue analysis

Recently, the National Symposium on New Technologies and New Product Exchanges for the Detection and Monitoring of Pesticide Residues in China, co-sponsored by the China Association for Agricultural Science and Technology Services, the China Agricultural Science and Technology Service Alliance, the China Agricultural Resources Quality Network, and the National Agricultural Science and Technology Service Network, was opened in Shenzhen. Curtain. Many experts and professors from agricultural inspection agencies, entry-exit inspection and quarantine agencies, third-party testing agencies, disease control agencies and universities from all over the country attended the seminar. The 11 meeting reports related to pesticide residue testing standards and status, impacts of pesticide residues on human health, impacts of pesticide residues on import and export trade, application of multiple pesticide residue detection methods, and research progress on agricultural residue degradation technologies. Covers the entire process of pesticide production, use, residue, and degradation. Shimadzu Corporation actively participated in this seminar.

With the improvement of the food safety requirements of our people, the standardization of agricultural products production and the standardization of the use of pesticides have received attention, and the detection of pesticides has also developed toward the direction of rapidity, accuracy, and automation. The on-line pre-processing GPC-GCMS system developed by Shimadzu Co., Ltd. connects liquid chromatography, gas chromatography and mass spectrometry instruments through a special interface to enable rapid pretreatment of samples and simultaneous analysis of multiple residues, making the original complicated. Pesticide residue analysis has become very simple, which provides a new method for the detection of pesticide residues.

The system consists of a GPC purification pre-treatment unit and GCMS on-line connection. Shimadzu's unique high-pressure liquid chromatography switching technology is used to automate the analysis process. The mini-GPC column and the newly developed GCMS large-volume injection method have been implemented. Simultaneous rapid analysis of multiple components of pesticide residues, while all sensitivity meet the 0.01ppm limit standard, the cost of analysis is also greatly reduced, with significant features such as high efficiency, high recovery rate, high sensitivity, and low analysis cost.

At present, many national and provincial-level key units such as the China Center for Disease Control and Prevention, the Ministry of Agriculture Vegetable Inspection Center, the Shanghai Entry-Exit Inspection and Quarantine Bureau, the Beijing Center for Disease Control and Prevention, and the Beijing Agricultural Environment Monitoring Station have already installed and used the island. The Tianjin GPC-GCMS on-line analysis system has undertaken various scientific researches and a large number of routine analysis and inspections. The outstanding performance and outstanding performance of GPC-GCMS have attracted the attention of experts in the industry.
