METHOD FOR ANALYZING AGRICULTURAL CHEMICALS USING LIQUID CHROMATOGRAPHY-TANDEM MASS SPECTROMETRY (LC-MS/MS)

摘要

PPROBLEM TO BE SOLVED: To provide a method capable of collectively analyzing agricultural chemicals, which have been separately analyzed, by achieving commonality of preparation processes of test liquids. PSOLUTION: The method for analyzing agricultural chemicals includes: a process (A) for adding water to a sample, keeping it as it is for some time, acquiring an extract solution with acetone or acetonitrile; a process (B) for condensing the extract solution acquired in the last process; a process (C) for extracting a solid phase by injecting the condensed extract solution into a diatomite packed column; a process (D) for removing a solvent of an effluent acquired by the solid-phase extraction and adding an organic solvent to a residue to acquire a test solution; and a process (E) for analyzing agricultural chemicals by measuring the test solution by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The agricultural chemicals are 2,4,5-T, cyhexatin, imidacloprid, piperonyl butoxide, and methoprene. PCOPYRIGHT: (C)2007,JPO&INPIT
