Our company cooperated with experts from China Agricultural University and spent 3 years developing a rapid pesticide residue detector, as well as its supporting reagents acetylcholinesterase, enzyme tablets, and color development tablets Recently obtained national patent.
This rapid pesticide residue detector uses the enzyme inhibition method to detect organophosphorus and carbamate pesticide residues. The use of solid-state variable light and sample liquid decolorization and impurity removal technology greatly reduces detection errors. The enzyme source used is acetylcholinesterase extracted from the heads of sensitive houseflies by Shandong Jingpeng Biopharmaceutical Co., Ltd., and the detection cost is lower than imported enzymes. More than 50%, the instrument adopts text and voice dual prompt operation, which is easy to use; the four detection channels can detect independently without affecting each other. It only takes 10 minutes to detect a sample individually. If the continuous detection time does not exceed 2 minutes, pesticide residues will be detected quickly. The power supply of the detector is 3 AA dry batteries, which breaks the situation that ordinary instruments cannot be used in the fields.
The detection reagents (enzyme tablets, chromogenic tablets) adopt a series of new processing technologies, so that they can be stored at room temperature and are very convenient to use (just cut off a piece when using). The acetylcholinesterase in the enzyme tablets is extracted and produced by our company exclusively from sensitive houseflies (note: our company is the only manufacturer in mainland China that produces acetylcholinesterase). Its sensitivity and stability are superior to imported enzyme sources.
