| titleOfInvention | A kind of method for measuring impurities in pesticide boscalid |
| abstract | The invention relates to the technical field of pesticide detection, in particular to a method for determining impurities in the pesticide boscalid, comprising the following steps: S1. respectively weighing boscalid impurity I and boscalid impurity II as reference substances, Then take acetone as solvent to prepare corresponding reference substance mother liquor 1 and reference substance mother liquor 2 respectively, mix in proportion to obtain impurity mixed reference substance solution; S2, take pesticide boscalid, and prepare sample solution with propanol as solvent; S3, use gas chromatography-mass spectrometry to measure the impurity mixed reference solution and the sample solution respectively. In the present invention, gas chromatography-mass spectrometry is used to detect possible by-products and impurities in the original drug of boscalid, the mixture of the original drug product is separated by gas chromatography, and the high-quality resolution and high sensitivity of mass spectrometer are used to detect the possible by-products and impurities of the original drug. Analysis and comparison of compound ions and ion fragments of secondary mass spectrometry can accurately identify the information of impurities contained in the pesticide boscalid. |
