Mainly for fruit, vegetables, tea, food, water, and soil organic phosphorus and carbamate pesticides rapid detection, especially for food safety inspection agencies at all levels of law enforcement to use the site, but can also be used tea fruit and vegetable production bases and farmers wholesale market scene detection, restaurants, canteens, family and other fruits and vegetables safe speed test before machining
1, the 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 food semi-quantitative detection.
2, biochemical reaction principle: speed test card cholinesterase (white tablet) catalyzes the indophenol acetate (red tablets) hydrolyzed to acetic acid and indophenol, as organophosphate and carbamate pesticides on cholinesterase inhibit enzyme activity, so the color change after catalyzed hydrolysis. Thus, according to the results of the color depth, you can determine the residual cases in the sample organophosphate or carbamate pesticides
