In reactions such as photocatalytic water splitting and CO₂ reduction, the target products are mostly gases (H₂, O₂, CO, CH₄, and so on). Traditional offline sampling requires stopping the light, collecting the gas, and then sending it to a chromatograph—this interrupts the photoreaction, introduces human error, and cannot capture the dynamic inflection point of product generation. The value of the μGAS1001 micro-gas reaction evaluation system is precisely to turn "reaction – sampling – detection" into a closed loop: the gas inside the reactor is automatically introduced into the gas chromatograph, peaks are quantified on a set cycle, and the entire process runs without manual intervention.
The complete system consists of three parts: the photocatalytic reaction system provides a controlled light and atmosphere environment; the PLD-CGA1000 compound gas analyzer or sampling valve feeds the trace gas into the chromatographic column; and the gas chromatograph performs separation and quantification. The three are linked through tubing and a timed program, forming a loop of "photoreaction → online injection → chromatographic quantification → data feedback."
| Module | Function | Key metrics |
|---|---|---|
| Photocatalytic reaction system | Provides light and a gas–solid / liquid–solid reaction environment | Air tightness, illumination uniformity |
| Injection & carrier-gas unit | Feeds trace gas into the chromatograph | Dead volume, response speed |
| Gas chromatograph | Separates and quantifies each gas component | Detection limit, repeatability |

The μGAS1001 is the complete micro-gas reaction evaluation system, while the gas chromatograph is its detection unit. The system links the photocatalytic reactor, injection valve, and gas chromatograph to achieve automatic quantification of produced gas.
Online analysis does not interrupt the photoreaction, programmatic injection eliminates human error, and it continuously records how products change over time—making it far easier to capture kinetic inflection points.
The reactor, injection, and chromatograph must be linked together. Perfectlight offers the complete μGAS1001 package and also supports integration with existing modules such as the PCX-50C and PLD-CGA1000.
