Analysis method of Oxine-copper remaining in agricultural products

摘要

The present invention does not require the examination of a mobile phase, and is also excellent in sensitivity, to provide a method for analyzing a simple pretreatment method. In the method of analyzing residual components of oxine-copper, first, 10 mg of oxine-copper is dissolved in 0.1 L of pyridine to prepare 100 mg / L, which is diluted with acetonitrile to be a standard product. After preparing an analytical sample consisting of homogenized fruit or vegetable, extracting and distributing the analytical sample with acetonitrile reagent and preparing an analytical solution by dispersive SPE purification method, GC-MS Mass spectrometer is used for the instrumental analysis of standards and sample liquids for the preparation of / MS calibration curves.
