The CEL-GPPCN is a professional system for gas phase photocatalysis, designed to perform the distribution and mixing of multiple gases with high precision. The system uses Mass Flow Meters (MFMs) to achieve ** arbitrary gas ratios** on demand. It is ideal for online testing systems in continuous reactions, gas-solid catalysis, and pollutant degradation.

Key Technical Features:

• Precise Flow Control: Equipped with Mass Flow Meters (MFMs) that ensure strict flow control and allow for gas mixing with 0.1 percent accuracy.

• Multi-Flow Distribution System: Four-way pneumatic circuit (three for flow control, one for purging), complete with an inlet filter and check valve.

• Temperature-Controlled Mixing Chamber: Features a 100 mL mixing chamber and pipelines with temperature control (from room temperature up to 200 degrees Celsius).

• Pressure-Resistant Design: The system has a pressure-resistant design of 2.0 MPa, with pipelines and valves made of 316L Stainless Steel (imported Anlok needle valves and fittings).

• Cutting-Edge Applications: Used in: Continuous Phase Photocatalysis, Gas-Solid Catalysis, Gas-Liquid Catalysis, Pollutant Degradation (VOCs, etc.), $\text{CO}_2$ Fixation, and Thermophotocatalytic Synthesis.

• Outlet Piping: Uses self-limiting temperature-heated stainless steel outlet piping.

• Reactor Flexibility: Compatible with a variety of reactors (Tripod Reactor, Integrated Temperature Control Reactor, High Pressure Reactor, and National Standard Reactor), and can be coupled with Xenon, Mercury, and LED light sources.
