Instrument model: HW-SJ10NC

Scope of use:
Portable pesticide residue detectorIt is a specially designed instrument based on the national standard method - rapid testing card method (paper method). Mainly used for rapid detection of organic phosphorus and carbamate pesticides in fruits, vegetables, tea, grains, water, and soil, especially suitable for on-site law enforcement by food safety testing institutions at all levels. In addition, it can also be used for on-site testing in fruit and vegetable tea production bases and agricultural wholesale sales markets, as well as safety rapid testing in restaurants, canteens, and households before fruit and vegetable processing.

detailed description:

1、 Instrument detection principle: Using a microcontroller to control parameters such as temperature and time, combined with biochemical reactions for semi quantitative detection of organic phosphorus and carbamate pesticides in vegetables, fruits, and other foods.
Biochemical reaction principle: Acetylcholinesterase (white tablet) in the rapid test card can catalyze the hydrolysis of indophenol acetate (red tablet) into acetic acid and indophenol. Due to the inhibitory effect of organophosphorus and carbamate pesticides on acetylcholinesterase activity, the color of the catalyzed hydrolysis changes. Therefore, based on the color intensity of the results, the residual situation of organophosphorus or carbamate pesticides in the sample can be determined.
