NY-8DA/16DA Pesticide Residue Meter
NY-8A/16DA Pesticide Residue Rapid Detector is developed based on the principle of enzyme inhibition and photoelectric colorimetry, which can realize rapid on-site detection of organophosphorus and carbamate pesticide residues. The pesticide residue rapid detector is widely used in the detection of pesticide residues in vegetables and fruits in product quality supervision and inspection, sanitation and epidemic prevention, environmental protection, business management, vegetable wholesale markets, vegetable production bases, supermarkets, shopping malls, pesticide residue monitoring systems and other departments.
Principle of Instrument.
Under certain conditions, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase, and the inhibition rate is positively correlated with the concentration of pesticides. Under normal circumstances, the enzyme catalyzes the hydrolysis of the nerve conduction metabolite (acetylcholine), and the hydrolysis product reacts with the chromogenic agent to produce a yellow substance. The change in absorbance at 412 nm with time is measured with a spectrophotometer, and the inhibition rate is calculated. It can quickly determine whether the sample contains residues of organophosphorus or carbamate pesticides.
