Full-Process Practice of Online Gas Analysis in Gas-Solid Photocatalytic Reactions: From Loading to Data | Perfectlight

1. Characteristics of Gas-Solid Systems

Gas-solid photocatalysis places powder or sheet catalysts in a flowing atmosphere under illumination; products are carried away by the carrier gas and detected downstream. Compared with liquid-solid systems, it more easily achieves continuous injection, making it a natural fit for online gas analysis.

2. Six Steps of the Full Process

Loading: spread the catalyst evenly on the reaction window, avoiding excessive piling that blocks light;
Atmosphere exchange: use the PLD-DGCS05 Multi-Component Dynamic Gas Distribution Instrument to establish the target atmosphere and purge air;
Leak test: confirm no leakage under positive-pressure holding;
Illumination: irradiate at the set intensity with a Xenon Lamp Light Source;
Online injection: the μGAS1001 sends gas into the gas chromatograph on a cycle;
Interpretation: plot the yield–time curve and calculate rate and selectivity.

3. Cooperation Between PLR-GSPR and μGAS1001

The PLR-GSPR Atmospheric-Pressure Gas-Solid Photocatalytic Reaction System provides a stable gas-solid illumination environment, and the μGAS1001 handles downstream online reading. Connecting them in series forms a "reaction–detection" closed loop without manual sampling.

4. Wrap-Up and Re-Check

After the experiment, re-check the chromatographic response factor with standard gas, and record the actual light intensity with the PL-MW2000 High-Intensity Light Power Meter, ensuring the data is archivable and reproducible.

Frequently Asked Questions (FAQ)

Why is gas-solid suitable for online analysis?

Products are continuously carried away by the carrier gas, naturally fitting downstream automatic injection without manual sampling.

What are the steps of the full process?

Six steps: loading, atmosphere exchange, leak test, illumination, online injection, and data interpretation.

How do the PLR-GSPR and μGAS1001 cooperate?

The PLR-GSPR provides a stable gas-solid illumination environment, and the μGAS1001 handles downstream online reading; connecting them in series closes the loop.
