| titleOfInvention | A kind of GC-NCI-MS assay method of Rynaxypyr residual quantity |
| abstract | The invention discloses a kind of GC-NCI-MS assay method of Rynaxypyr residual quantity, the method is mainly used in measuring the method for Rynaxypyr content residual in the complex matrices such as Cereals, animal derived food food agricultural product. Extract residual Rynaxypyr in sample, C with acetonitrile or containing the acetonitrile solution homogeneous of 1% acetic acid 18 After/PSA SPE column purification is concentrated, Gas Chromatography-Negative chemical ionization source-mass spectrum (GC-NCI-MS) detects, and adopts the not vehicle solution containing agricultural chemicals to be measured to set up the calibration curve of proofreading and correct, and external standard method is quantitative. This method average recovery rate is 86.8%～96.9%, average relative standard deviation (RSD) is 4.0%～9.7%, detection limit is lower than 1.41 μ g/kg, have easy and simple to handle, quick, impurity elimination is effective, highly sensitive, characteristic is strong, reproducible, qualitative, quantitative advantage accurately. Can meet the 0.01mg/kg residue limits of the countries such as the U.S., Japan, European Union, Canada to corresponding food safety detection, the i.e. technical requirement of " uniform limit ", will provide strong technical support for ensureing that Chinese people people's food security and export abroad trade develop in a healthy way. |
