A ﹑ machine Name: pesticide residue detector Second, Model: CSY-N48 three, pesticide residue testing Instrument Introduction: CSY-N48 pesticide residues detector according to standard methods based on agriculture (NY / T 448-2001) and national standards ( GB / T5009.199-2003) of enzyme inhibition rate method, strictly abide by the "vegetable organophosphorus and carbamate pesticide residues rapid test method standards" in the provisions of the vegetables of organophosphorus and carbamate pesticide residues Rapid determination. Is the first generation of pesticide residues detector upgrade products, can accurately and quickly detect the rapid detection of vegetables, fruits, grains, tea and soil organic phosphorus and carbamate pesticide residues in lipids. Can be widely used at all levels of government testing center vegetables, farmers markets, supermarkets, environmental agencies, vegetable planting base, hotel, car and food safety testing laboratories and other units of measurement and monitoring sites for pesticide residues in fruits and vegetables. Fourth, the pesticide residue testing Instrument Principle: Based on pesticide residues detector enzymatic reaction dynamics, the test sample as containing phosphorus or carbamate pesticides, will inhibit cholinesterase activity, the impact of the color system The reaction rate by measuring the absorbance of the color system to measure the time rate of change of the sample of pesticide residues (inhibition). _ Organophosphate and carbamate pesticides on the normal function of cholinesterase inhibition, inhibition rate and pesticide concentrations showed a positive correlation. Under normal circumstances, the enzymatic neurotransmitter metabolites (acetylcholine) hydrolyzing reagent reaction hydrolyzate thereof, to give a yellow substance, measuring the absorbance change value with time pesticide residue testing instrument to calculate the inhibition ratio by the inhibition rate based on whether the sample contains the presence of organophosphate or carbamate pesticides. Fifth, pesticide residues Detector Specifications: ☆ wavelength range: 300nm-1000nm ☆ Wavelength accuracy: ± 2nm ☆ absorbance range: 0.000 ~ 4.000ABS ☆ Resolution: 0.001Abs ☆ Stability: ± 0.001A / hr ☆ transmittance repeat sex: ≤0.5% T ☆ source: imported LED ☆ sample pool: Microplate ★ 48-channel design, 9-channel optical system, which detects the optical path signal source for eight 48-well plates.
