Gas chromatography: This method is used for analysis and testing 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 relative difference between the retention time of the chromatographic peak of the sample solution and the retention time of the chromatographic peak of the standard solution should be within 1.5%.
