CEL-SPH2N-S9 double reflective catalytic activity evaluation system
Introduction: The CEL-SPH2N-S double-reflector series photocatalytic activity evaluation system (also known as the double-reflective photo-hydrogen production system) uses a variety of valve combinations to collect and analyze samples (in compliance with the national standard GB/T26915-2011), which can be used for photolysis of water to produce hydrogen , Photolysis of water to produce oxygen and room temperature and pressure photocatalytic reduction of CO2 experiments;Function application: qualitative and quantitative product, and light quantum efficiency test. Two sets of integrated reaction system (double reverse series), two sets of independent non-interference equipment, one set of space occupation, 1.5 times the price of SLR series, solve the shortage of laboratory space and save a lot of scientific research funds. Two sets of independent use, joint use, parallel sample testing can be realized, and the efficiency of scientific research can be improved. Features: 1. Automatic dual-experiment integrated photolysis water hydrogen production instrument, realize two parallel experiments without interference, and glass valve system at the same time; 2. Contains 4 sets of independent fully automatic control valves, fully automatic control and anti-control software, and the system is fully computer controlled, without cumbersome valve operations; 3. The glass high vacuum system circulation pipeline adopts patented technology 4. High-efficiency circulating pump, instant mixing in 1 second, no need to wait, sampling at any time, mixing speed 1.8L/min; 5. Used for trace gas reaction and product detection, the volume of the system circulation pipeline is less than 150mL; 6. It is equipped with a multi-functional buffer gas storage device as standard, which can be connected to a spare gas tank; 7. According to the user's habits, the national standard six-way valve, four-way valve, three-way valve, two-way valve and multiple combinations of the above valves can be selected. The material can be corrosion-resistant stainless steel, glass, PTFE, and the control can be manual or semi-automatic. , Fully automatic; 8. The sampling part of the SLR system has no dead volume and no blow-up phenomenon; 9. Standard reactor with double-layer thermostatic water jacket (250ml/100ml/50ml optional), pressure-resistant full-spectrum high-transparent quartz window; 10. Built-in gas shut-off protection function can ensure the safety of gas chromatography GC under misoperation (such as insufficient carrier gas pressure); 11. With 2 sets of standard injectors (including gas injection needles); 12. The light source equipment is placed behind the system, and the installation and disassembly of the reactor does not need to move the light source; 13. Using stainless steel bellows KF16, 1.8m, no vibration, clean and pollution-free, can be bent arbitrarily, standard multi-purpose interface, can be connected with various vacuum pumps. Technical Parameters: Vacuum degree: relative vacuum degree -0.1Mpa (more than 72 hours, dynamic test); absolute vacuum degree <3×10-4Mpa (PV=nRT). Vacuum characterization: relative pressure precision vacuum gauge, accuracy level 0.4 (standard); Relative pressure digital vacuum gauge is optional); absolute pressure digital vacuum gauge, accuracy 0.1Pa (optional); Hydrogen production test range: 0.1 microliter ~ 100ml (expandable 1000ml), precision PPM level; Linear regression of standard curve: K>0.9999 (the actual measurement is 1) Quantitative sampling: 0.5ml/1ml/1.5ml/2.2ml/3ml optional, multiple sampling without error, avoiding misoperation; Condensation system: snake cooling + direct cooling double-layer cooling device (optional spherical cooling or direct cooling); Vacuum pump: domestic or imported brand vacuum pump, with anti-oil back-suction function, pumping rate 2L/s;
