Preparation and evaluation of acetamiprid quality control samples in rapeseed stalk
摘要
Abstract
In order to ensure the accuracy and reliability of the rapid determination of acetamiprid pesticide residues in rapeseed stalk,a method for the preparation of quality control samples was established and evaluated.The lyophilized quality control samples were prepared by matrix spiking and vacuum freeze-drying.And the deter-mination of acetamiprid in the quality control samples was carried out by liquid chromatography-tandem mass spec-trometry.The uniformity of the samples was assessed by random sampling and the stability of the samples was evalu-ated by observing the changes of acetamiprid over a period of one month.The quality control samples prepared by this method are homogeneous and stable,easy to store and transport,and suitable for rapid testing in the field of rap-id test kit validation and blind sample assessment.This study established a simple process for the preparation of lyophilised powder quality control samples of rapeseed stalk,which provides a data reference for the study of com-mon key technologies for the preparation of quality control samples of pesticide residues in vegetables.关键词
