AI Technical Summary

Technical Problem

Current technologies lack rapid and accurate methods for detecting residues of clethodim, pyriflusulfonamide, and triazole chlorpyrifos in animal feed, especially for high-boiling-point herbicides, which makes it impossible to effectively protect animal health and human food safety.

Method used

By employing dispersion solid-phase extraction pretreatment technology combined with ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), rapid and accurate detection of these three herbicides in feed can be achieved through sample pretreatment, impurity adsorption, and purification steps.

Benefits of technology

This invention provides a highly sensitive and specific detection method that can rapidly and accurately determine the residues of clethodim, pyriflusulfonamide, and triazole chlorpyrifos in feed, reducing operational complexity and cost while improving the reliability of detection results.
