First, the product name: portable detector two pesticide residues, Model: CSY-N12 three portable pesticide residue detector Products: CSY-N12 portable pesticide residue detector is based on GB method --- speed test card method (paper Method) and specially designed equipment. Mainly used for fruit, vegetables, tea, food, water, and soil organic phosphorus and rapid detection of carbamate pesticides, especially for food safety testing site enforcement agencies at all levels to use, portable pesticide residues in fruits and vegetables can be used for tea detector production bases and farmers wholesale market scene detection, security and other speed measurement restaurants, canteens, family fruit and vegetable processing ago. Fourth, portable pesticide residue detector Details: Instrument detection principle: the use of single-chip temperature and time parameters of control, with biochemical reactions to organophosphate and carbamate pesticides vegetables, fruits and other foods were semi-quantitative detection. Biochemical reaction principle: speed measurement card cholinesterase (white tablets) catalyzes the indophenol acetate (red pill) is hydrolyzed to acetic acid and indophenol, due to organophosphate and carbamate pesticides on cholinesterase inhibitory activity, so that the color change after the catalyzed hydrolysis. Thus, according to the results of the color depth, you can determine the residual cases samples organophosphate or carbamate pesticides.
