Introduction: The CEL-PAEM-D8 photocatalytic activity evaluation system upgrades the original conventional photolysis water system, and integrates the glass system into a closed light-shielded box, which is easy to move and is not easily damaged. It is suitable for the low-hydrogen production, and the cost of the catalyst is more expensive, which is more conducive to the verification of the concept of full solution. Realize online automatic unattended test analysis; manual and fully automatic sampling methods are available. Features: 1. Micro-reaction system, very low catalyst dosage; 2. Activity evaluation of semiconductor materials (TiO2, C3N4, CdS, etc.) 3. Performance analysis of hydrogen production and oxygen production by catalyst 4. Performance analysis of catalyst carbon dioxide reduction 5, can be configured with special experimental requirements such as photoelectric reaction, gas-solid reaction, membrane catalysis; closed and integrated design, the panel uses translucent plexiglass plate, all closed plates can be taken out at any time for easy maintenance; 6. Online automatic unattended test analysis; 7, can choose manual, semi-automatic, fully automatic sampling mode; 8, easy to install, can be compatible with any manufacturer gas chromatograph; 9, a wide range of tests, hydrogen, oxygen, CO2, methane, CO, formaldehyde and other trace gases; Technical Parameters: 1. All the pipes are made of glass, and the patented glass valve is used for injection. The pipeline gas circulation adopts 1.8L/s corrosion-resistant fan; 2. The reactor volume is 100ml, 250ml, 25ml, 50ml; 3. Pipe volume 50ml ± 5, vacuum -0.1MPa (72h dynamic); 4. Sampling method: manual, semi-automatic, fully automatic; 5. Control mode: software automatic control (8-bit); automatic execution status, real-time display, software interface; USB and RJ45; 6. Test accuracy, 0.01ml & 0.01min; 7. Vacuum pump, reverse control automatic start and stop, 2L / s, with anti-back suction solenoid valve; 8. The light source is placed, the light source is still placed on the back end platform of the system, which is more stable, easy to replace the reactor and sample pick-and-place; 9. Test range: hydrogen, oxygen, CO2, methane, CO, formaldehyde, acetaldehyde and other trace gases, H2, O2 > 0.001ml; CO, CO2, CH4 > 1ppm; CH3OH, HCOOH, CH3CH2OH, CH3COOH > 10ppm; 10. The glass gas path has a built-in U-shaped cold trap line for increasing the vacuum and separating volatile solvents; 11. The vacuum pump is equipped with a stainless steel liquid nitrogen trap, and the KF16 connector is used to realize the double cold trap configuration in the system; 12. Closed design, all closed panels can be taken out at any time to facilitate maintenance of the glass system. The panel uses a translucent plexiglass plate to observe the situation in real time and prevent light pollution, 560mm (width) * 470mm (deep) * 860mm (height).
