Description

technical field [0001] The invention relates to a QuECHERS pretreatment technology, in particular to a fully automatic QuECHERS experimental device and an experimental method. Background technique [0002] The development of agricultural industrialization makes the production of agricultural products more and more dependent on exogenous substances such as pesticides, antibiotics and hormones. The amount of pesticides used in agricultural products in my country remains high, and the unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products , affect the safety of consumers, and in serious cases will cause consumers to become ill, develop abnormally, etc., and even directly lead to poisoning death. Excessive pesticide residues will also affect the trade of agricultural products. Countries around the world attach great importance to the issue of pesticide residues, and have set increasingly strict limits for agricultural re...
