| titleOfInvention | A kind of assay method of metrafenone residual quantity |
| abstract | The invention discloses the assay method of a kind of metrafenone residual quantity, the method is mainly used in measuring the method for the metrafenone content of residual in the complex matrices food agricultural product such as Cereals, animal derived food.The metrafenone of residual, C in sample is extracted with acetonitrile or the acetonitrile solution homogenizing containing 1% acetic acid 18 After the concentration of/PSA Solid-Phase Extraction column purification, Gas Chromatography-Negative chemical ionization source-mass spectrum (GC-NCI-MS) detection, adopt the vehicle solution without pesticide to be measured to set up the standard curve of correction, quantified by external standard method.This method average recovery rate is 83.9%～90.1%, average relative standard's deviation (RSD) is 4.0%～5.8%, detection limit lower than 0.67 μ g/kg, have easy and simple to handle, quick, roguing is effective, highly sensitive, characteristic is strong, reproducible, qualitative, quantitative advantage accurately.European Union, the U.S., Korea S, the Japan and other countries technology requirement to corresponding product safety detection can be met, for ensureing that our people's food safety and export abroad trade sound development provide strong technical support. |
