Rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues Instrument Description: CSY-N8 rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues in accordance with the method according to the Agricultural Standards (NY / T 448-2001) and national standards (GB / T5009. 199-2003) the enzyme inhibition rate method, strictly follow the "vegetables organophosphate and carbamate pesticide residues rapid detection method standards" in the provision of rapid determination of residual vegetables organophosphorus and carbamate pesticides. Is the first generation of pesticide residues detector upgrade products that can accurately and quickly detect the rapid detection of vegetables, fruits, grain, tea and soil organic phosphorus and carbamate pesticide residues in lipids. Rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues can be widely used in government at all levels of vegetable testing center, farmers market, supermarket, environmental agencies, vegetable planting base, hotel, car and other food safety testing laboratories and monitoring sites and other units determination of pesticide residues in fruits and vegetables. Fourth, rapid detection of pesticide residues in fruits and vegetables _ pesticide residues rapid detection principle: rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues based on the principles of enzymatic reaction kinetics, such as the sample containing phosphorus or carbamate pesticides will inhibit the activity of cholinesterase reaction speed impact color system, the color system by measuring the absorbance of the sample to measure the amount of pesticide residues (inhibition rate) rate of change over time. _ 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. Fifth, rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues technical parameters: ☆ precision error: ± 3% ☆ linearity error: ± 5 ‰ ☆ Stability: ± 0.001A / hr ☆ Wavelength accuracy: <2.0nm ☆ absorbance Range: 0.000 ~ 4.000ABS ☆ wavelength range: 410nm ± 2nm ☆ Transmittance Repeatability: ± 1% ☆ ☆ sample data storage 80,00 stripe detection time: ≤3 minutes ☆ cuvette: 10 × 10mm standard cuvette ☆ Appearance Dimensions: 350X290X130 (mm) ★ rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues using the new instrument design, small size, easy to carry. No mechanical moving parts, jamming, anti-vibration, ★ 8-channel design, and start and single, respectively, to start two measurement modes. When multiple sample measurements, customers can operate proficiency, choose the measurement mode, the maximum coefficient of variation between channels to 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 fruit and vegetable pesticide residues rapid detection of the degree of automation _ instrument for rapid detection of pesticide residues: the instrument automatically diagnose system failures, wavelength calibration: automatic calibration instrument ★ Long life: LED light, automatic switching 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 reports can be printed vegetable names, inhibition rate, eligibility, testing date, test units. Better reflect the test results of the authority, and to facilitate public ★ rapid detection of pesticide residues in fruits and vegetables _ rapid detection of pesticide residues 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, according to user requirements at all levels of the network set up provincial, city, prefecture, county and so on. http://www.csy17.com/pro543.html
