| titleOfInvention | A kind of GC-NCI-MS assay method of spiral shell worm ethyl ester residual quantity |
| abstract | The invention discloses a kind of GC-NCI-MS assay method of spiral shell worm ethyl ester residual quantity, the method is mainly used in the method measuring spiral shell worm ethyl ester content residual in the complex matrices such as Cereals, animal derived food food agricultural product.Spiral shell worm ethyl ester residual in sample is extracted, C with acetonitrile or containing the acetonitrile solution homogeneous of 1% acetic acidn 18 after/PSA Solid-Phase Extraction column purification is concentrated, Gas Chromatography-Negative chemical ionization source-mass spectrum (GC-NCI-MS) detects, and adopts and does not set up the typical curve corrected, quantified by external standard method containing the vehicle solution of agricultural chemicals to be measured.This method average recovery rate is 86.5% ~ 91.7%, average relative standard's deviation (RSD) is 4.1% ~ 7.6%, detection limit lower than 4.72 μ g/kg, have easy and simple to handle, quick, impurity elimination is effective, highly sensitive, characteristic is strong, reproducible, qualitative, quantitative advantage accurately.The U.S., European Union, Japan and other countries being met to the technical requirement of corresponding food safety detection residue limits, providing strong technical support by for ensureing that our people's food security and export abroad trade develop in a healthy way. |
