Scope

Scope: This standard specifies the gas chromatography-mass spectrometry method for analyzing 88 pesticide residues in tea leaves (see Appendix A1). This standard is applicable to the determination of 88 pesticide residues in tea leaves. Main technical content: After the sample is soaked in water, it is extracted with acetonitrile. The extract is purified by solid-phase extraction and detected by gas chromatography-mass spectrometry. The retention time and ion abundance ratio are used for qualitative analysis, and the quantitative analysis is performed by internal standard method or external standard method.
