Gaschromatographie-Tester

Gas chromatography,model GC9801 Function and usage: 1. Carry out the quantitative analysis and peculiar smell testing for residual solvent on food packaging cases after printing. 2. Test the pureness and quality of organic solvents. Product charactoristic: 1. It can be connected to the chromatogram data work station; 2. Greatly improve the working efficiency; 3. It has eight-step temperature rise; 4. The configuration can be made as per your requirements and five detectors can be chosen and used according to the analytic requirements: 1) Hydrogen flame ionization detector (FID) – for organic compounds analysis with high sensitivity 2) Thermal conductivity detector (TCD) – used to analyze permanent gas, water and low-carbon mix. 3) Flame photometric detector (NPD) – applicable for analysis of pesticide residue, sulphur and phosphorous. 4) Electron capture detector (ECD) – applicable for analysis of pesticides and chlorine solvent. 5) Nitrogen and phosphorous detector (NPD) – applicable for the detection of trace amount of nitrogen and phosphorous 6. With the flexible design of the packed column and capillary column injection ports (Packed column and capillary column sample injectors can be selected as per actual situations); 7. Wide column box (300mm×300mm×200mm); 8. use various chromatographic columnsto widen the range of the analytic samples; 9.use advanced noise suppression system to avoidnoise and keep quiet when working; 10. The sampling device is completely vitrified with two modes of rapid vaporizing and column sample injection; 11. Brand-new pressure stabilization and various air circuit system; 12 Reforming furnace can be equipped to implement microanalysis of CO and CO2; 13.With microcomputer control; 14.Advanced temperature control system; 15. Temperature control scope: (room temperature +10°C) - 400°C, eight-step temperature rise; 16. The speed is 0 - 30°C/min (with increase 0.1°C/min), and the temperature control precision is 0.1%. 17. The control point number is eight points of A type and control scope (room temperature +10°C) is - 400°C. 18. Overheat protection function 19. It can freely set any temperature within 400°C and is provided with double fail-safe design of software program protection and hardwired connection.
