T/GZTPA 0008-2020 The detection of hidden-offensive organophosphates in herbicide emulsifiable concentrates using gas chromatography method
Basic Information
Scope
Scope: This standard specifies the gas chromatography analysis method for ten prohibited highly toxic organophosphorus pesticides (see Appendix A) in emulsifiable pesticides. This standard is applicable to the gas chromatography analysis of prohibited highly toxic organophosphorus pesticide components in emulsifiable pesticides using a gas chromatography flame photometric detector. Main technical content: Gas chromatography: - This method is used for the analysis of active ingredients in daily samples. - This identification test can be conducted simultaneously with the determination of pesticide content. - Under the same chromatographic operating conditions, the retention time of the chromatographic peak of the sample solution should be within a relative difference of 1.5% compared to the retention time of the chromatographic peak of the standard solution.
