The CEL-PAEM-D8PLUS is a professional, automatic evaluation system designed to measure photocatalyst activity, focusing on carbon dioxide reduction (CO2) and total water photolysis (H2O). Its integrated, closed design, featuring temperature control across all pipelines, ensures continuous and precise analysis of trace gases. The system is ideal for experiments involving high-value catalysts or complex trace reactions.

Key Technical Features:

• Automatic Professional Analysis: Automatically performs closed system analysis for $\text{CO}_2$ reduction and is compatible with water photolysis and total water hydrolysis.

• Integrated Closed Design: The glass system is integrated into a shading box, making it easy to move and reducing damage risk. The closed design with removable panels simplifies maintenance.

• Total Temperature Control: Adopts seven stages of temperature control, covering condensation reflux, circulation, sample collection, and analysis (up to 200 degrees Celsius), ensuring process accuracy.

• High-Quality Piping and Sampling: All pipelines are made of glass and use a patented glass valve for sampling.

• Flexible Sampling Modes: Allows selection between manual, semi-automatic, and automatic sampling modes. The automatic system features USB reverse control via software.

• Wide Test Range: The system is capable of detecting a wide range of trace gases, including Hydrogen, Oxygen, $\text{CO}_2$, Methane, $\text{CO}$ (with sensitivity greater than 1 ppm) and Aldehydes.

• Unattended Operation: Capable of performing automatic and online testing and analysis without constant intervention.

• Compatibility: Easy installation and compatible with any manufacturer of Gas Chromatograph (GC). The light source remains stable at the back end of the system platform.
