Problems solved by technology

However, the preparation and storage of samples and the pretreatment of samples involve a series of complex operations such as crushing, extraction, filtration, dilution, extraction, purification, and concentration of samples. First, the purpose, items and requirements of the analysis are also different. These processes are basically completed manually at present, and there are very few related fully automated equipment. Therefore, sample processing takes up most of the manpower and time in the entire analysis process, and Seriously affect the results and efficiency of analytical testing

Description

technical field [0001] The invention relates to the field of food safety analysis and detection, in particular to a fully automatic immunomagnetic bead purification instrument. Background technique [0002] Food safety testing is to detect harmful substances in food according to national indicators, such as heavy metal residues, pesticide residues, veterinary drug residues, food-borne pathogens, mycotoxins, illegal addition of non-edible substances and abuse of food additives in food. The general process of food testing and analysis is: sample collection, preparation and storage, sample pretreatment, component analysis, analysis data recording and collation, and analysis report writing. In the whole process, the method of component analysis is very mature, and the required detection instruments and equipment are complete, and the degree of automation and intelligence is relatively high, especially some large-scale analytical instruments, such as liquid mass spectrometry and ...
