CSY-N8 pesticide residue pesticide residue analyzer detector _ _ rapid determination of pesticide residues Instrument Introduction: CSY-N8 pesticide residue pesticide residue analyzer detector _ _ rapid determination of pesticide residues in agricultural instrument according to according to standard methods (NY / T 448- 2001) and national standards (GB / T5009.199-2003) the inhibition rate method, strictly follow the "vegetables organophosphate and carbamate pesticide residues rapid detection method standards" in the provisions of the vegetables organic phosphorus and amino formic acid esters rapid determination of pesticide residues. Is the first generation of pesticide residues detector upgrade products that can accurately and quickly detect the vegetables, fruits, grain, tea and soil organic phosphorus and carbamate pesticide residues lipid CSY-N8 pesticide residue analyzer detector _ _ Tester pesticide residues. Vegetables can be widely used in government testing centers at all levels, farmers markets, supermarkets, environmental agencies, vegetable planting base, hotel, car and other food safety testing laboratories and monitoring sites and other units of measurement for pesticide residues in fruits and vegetables. Four, CSY-N8 pesticide residue pesticide residue analyzer detector _ _ rapid determination of pesticide residues Instrument principle: CSY-N8 pesticide residue pesticide residue analyzer detector _ _ rapid determination of pesticide residues instrument based on the principle of enzymatic reaction kinetics, is test sample as containing phosphorus or carbamate pesticides, will inhibit cholinesterase activity, significantly influence the reaction speed of the color system, the color system by measuring the time rate of change in absorbance of the sample is measured in pesticide residues (inhibition). _ Organophosphate and carbamate pesticides on the normal function of cholinesterase inhibition, the inhibition rate of pesticide concentrations were positively correlated system. Under normal circumstances, the enzymatic nerve conduction metabolites (acetylcholine) hydrolysis, color-developing agent reactive hydrolyzate thereof, to give a yellow substance, measuring change in absorbance value over time with pesticide residue detection equipment, to calculate the inhibition rate, by an inhibition ratio can Analyzing whether the sample contains the presence of organic phosphorus or carbamate pesticides.
