Full-automatic QuECHERS experimental device and experimental method

Abstract

The invention discloses a full-automatic QuECHERS experimental device and an experimental method. The full-automatic QuECHERS experimental device comprises a multifunctional mechanical arm, a cap screwing module, a liquid adding module, a centrifugal module, a salt adding module, a ceramic proton homogenization module, a nitrogen blowing concentration module, a vortex uniform mixing module and anoscillation module, and can automatically complete sample transferring, addition of extraction liquid, extraction salt and ceramic homogenization protons, oscillation uniform mixing, centrifugal separation and vortex uniform mixing actions; A method adopting the full-automatic QuECHERS experimental device to carry out experiments mainly integrates the processes of sample liquid adding extraction,centrifugal separation, solid phase extraction and nitrogen blowing concentration, so that the time is saved, the manual operation is reduced, the automation is improved, and the errors are reduced.

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...
