Rapid development of rapid sample preparation equipment

Recently, the Chinese Institute of Inspection and Quarantine has developed three instrument prototypes for rapid sample preparation, vortex centrifugation and QuEChERS pretreatment, and applied seven colloidal gold test strips such as thiamphenicol. Meat products and vegetable foods are tested for safety. The limit of detection can meet the requirements of the national standard and resolve the worries of Beijing citizens.

In addition, a portable biosafety cabinet and a portable incubator have been developed to allow rapid processing and product testing of veterinary drug residues and pathogenic microorganisms in meat and vegetable foods. And obtained five kinds of immunomagnetic beads products such as clenbuterol hydrochloride, chloramphenicol, enrofloxacin, Escherichia coli O157:H7, and Listeria monocytogenes, and formed a market-oriented ability to ensure food safety in Beijing in multiple directions. The rapid sample processing of meat and vegetable foods can be achieved, which can replace imported similar products and has a broad market prospect.
