The CEL-SPH2N-D system (also known as the SLR water hydrogen production system) is a professional catalyst evaluation platform, designed to quantify products and test quantum efficiency. It adopts a combination of high-precision valves (in compliance with national standard $\text{GB/T26915-2011}$) and a high-level vacuum system design. It is a complete solution for research involving water photolysis and $\text{CO}_2$ reduction.
Key Technical Features:
-
Primary Applications: Used for Hydrogen production from water photolysis, Oxygen production from water photolysis, and photocatalytic $\text{CO}_2$ reduction at room temperature and pressure.
-
High-Precision Vacuum System: Achieves a relative vacuum degree of -0.1 MPa (dynamic test over 72 hours) or an absolute vacuum less than 3 x 10 to the power of negative 4 MPa. The circulation pipeline uses patent technology high vacuum glass.
-
Fully Automatic Control: Control valves are fully automatic and software-controlled, eliminating the need for tedious manual operation and ensuring repeatability. Sampling time and number of cycles can be set arbitrarily.
-
Trace Reaction System: The system circulation pipeline volume is less than 150 mL, ideal for detecting trace gas reaction products.
-
High-Efficiency Circulation Pump: Ensures instant mixing within 1 second and a circulation speed of 1.8 L/min, allowing for sampling at any time.
-
Wide Test Range: The hydrogen production test range is wide, from 0.1 microliter to 100 ml (expandable to 1000 ml), with PPM-level precision.
-
Stable Platform: Features a double-layer highly stable support platform to ensure the safety of glass instruments. The light source equipment is placed behind the system for easy reactor assembly/disassembly.
-
Compatibility: The system can be connected to Gas Chromatographs (GC) from various manufacturers (e.g., Shimadzu, Agilent) and different light sources (Xenon, LED).
-
Safety: Built-in gas protection function to ensure GC safety under misoperation (such as insufficient carrier gas pressure).
