Technical parameters and advantages of CEL-SLF-Vertex photoelectric chemical test and analysis system.

1. good light source stability, better than 0.5%; high integration, the system is integrated in an optical plate, the optical path is stable and easy to transport.

2. optical path is optimized to achieve maximum light output efficiency of 50mw/cm2; spectral range 300-1600nm, output bandwidth continuously adjustable, 0.1~30nm.

3. monochromator is equipped with a special port for nitrogen filling, which is convenient for use in the UV and NIR bands with atmospheric absorption spectrum; the optical room and mechanical drive room are strictly separated to avoid stray light from the latter and the pollution of the optical parts by trace volatilization of lubricating oil; the monochromator body is a one-piece structure of the casting to ensure the stability of the optical system.

4. computer software can realize real-time online control and data acquisition of xenon lamp light source, monochromator, filter wheel, shutter, optical power meter and electrochemical workstation.

5. automatic shutter Shutter is used to control the irradiation time (0.1ms),DK25; shielded darkroom 30cm*30cm*35cm, adjustable height.

6. reaction cell can be selected from the PECK series photoelectric reaction cell, and standard with applicable electrodes.

7. Standard equipped with Admiral Squidstat Plus electrochemical workstation, powerful software functions to achieve full coverage of electrochemical functions, especially in AC impedance EIS test, and can achieve secondary development and upgrading.

8. Standard with CEL-HXF300/HXUV300 series xenon lamp light source, can be used alone, but also with the filter to achieve photoelectric catalysis experiments.

9. The adjustable part of the light source covers the ultraviolet region, visible region, infrared region, there are many kinds of optional light sources, optional light sources are deuterium lamp, iodotungsten lamp, xenon lamp light source, mercury lamp light source, etc., of which xenon lamp is very widely used, and has a continuous full spectrum.

Advantageous features.

Photoelectrocatalytic reaction of semiconductor materials is a catalytic process carried out at the interface of two conductors with different types (electron and ion) conductivity, which has the characteristics of both photocatalysis and electrocatalysis. Photocatalytic method in recent years has received increasing attention to wastewater treatment technology, photolysis of water to produce hydrogen, catalytic reduction of CO2 to organic matter, nitrogen fixation to ammonia, etc., under the action of light and applied electric field, the electron-hole pairs are effectively separated, thus improving the role of catalytic efficiency. cel-SLF-Vertex photoelectric chemical test and analysis system is a photoelectric catalytic system independently developed by CEL-Jinyuan, which can be used with the U.S. Admiral, Germany Zahner, PINE, CHI and other electrochemical workstations, the system can be upgraded and developed twice to solve the customization requirements of customers. The photocatalytic system can achieve continuous wavelength adjustment, and is used in many fields such as material characterization, photoelectricity testing, electrochemical analysis, photocatalysis and IPCE testing.
