A ﹑ machine Name: pesticide residue detector Second, Model: CSY-N8 three, CSY-N8 pesticide residues Instrument Introduction: CSY-N8 pesticide residues detector according to standard methods based on agriculture (NY / T 448-2001) and National Standard (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 Rapid Determination of pesticide residues. 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. Four, CSY-N8 pesticide residues Instrument principle: pesticide residue detector enzymatic reaction kinetics based on the principle of the test sample as containing phosphorus or carbamate pesticides, will inhibit cholinesterase activity, influence reaction speed color system, the time rate of change in absorbance of the sample to measure the amount of pesticide residues (inhibition) by measuring the color system. _ 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. Five, CSY-N8 pesticide residues Detector Specifications: ☆ accuracy error: ± 3% ☆ Linearity error: ± 5 ‰ ☆ Stability: ± 0.001A / hr ☆ Wavelength Accuracy: <2.0nm ☆ absorbance range: 0.000 ~ 4.000 ABS ☆ wavelength range: 410nm ± 2nm ☆ Transmittance Repeatability: ± 1% ☆ ☆ sample data storage 80,00 stripe detection time: ≤3 minutes ☆ cuvette: 10 × 10mm standard cuvette ☆ Dimensions: 350X290X130 (mm ) ★ using the new instrument design, small size, easy to carry. No mechanical moving parts, jamming, anti-vibration, ★ 8-channel design, and start and single were started two measurement modes. When multiple sample measurements, customers can operate proficiency, self-select the measurement mode, the maximum coefficient of variation between channels eliminate caused by measurement error. ★ high accuracy: imported special LED light source, with good wavelength accuracy and repeatability, and comprehensively improve the accuracy of test results. ★ high degree of automation: the instrument automatically diagnose system faults, Wavelength Calibration: automatic calibration instrument ★ Long life: LED light source, automatic switch energy saving design, the non-continuous mode. ★ life of up to 10 years more than 8000 instrument automatically stores the measurement data. Built-in mini thermal printer, lifelong need to replace the ribbon, you can print the test results in real-time test report can be printed vegetable names, inhibition rate, eligibility, testing dates, testing units. Better reflect the authoritative test results, and to facilitate public ★ equipped with RS-232 interface and a USB port for data processing by computer, statistical analysis, and upload the results. The company as matching food safety monitoring network software, you can set up networks at various levels according to user requirements provinces, municipalities, the county and the like. http://www.csy17.com
