Bofeilai recently launched a new research equipment - the μGAS1000 Trace Gas Reaction Evaluation System, which has been put into use at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences since July this year, providing powerful research support.
The development of the μGAS1000 Trace Gas Reaction Evaluation System is not an overnight success but is based on Bofeilai's nearly 10 years of profound experience and technical accumulation in gas-tight glass reaction systems. In the process of research and manufacturing, Bofeilaike Technology has gone through numerous cycles of design-verification-modification, selecting the best solutions to ensure the equipment's excellent quality and performance.

The outstanding performance of the μGAS1000 Trace Gas Reaction Evaluation System allows it to fully meet the rigorous requirements of high data presentation, sensitivity, and gas tightness in the solar photocatalytic water splitting research at the Dalian Institute of Chemical Physics. This is of great significance for improving research accuracy and depth, promoting scientific progress in related fields.
The main body of the μGAS1000 Trace Gas Reaction Evaluation System integrates software and control unit, gas circulation and automatic sampling module, and reactor module, significantly improving ease of operation, system stability, and data accuracy.
μGAS1000 Trace Gas Reaction Evaluation System mainly features the following three key characteristics:
1. PC software control, real-time display of reaction process information and result data
The computer-side software of the μGAS1000 Trace Gas Reaction Evaluation System can integrate control of the system, gas chromatograph, and vacuum pump, and achieve integrated control through a controllable sampling structure (patented sampling valve island, patent number: 2022219141302). This innovation simplifies the operation process to some extent, reduces manual intervention, thereby improving operational accuracy and experimental efficiency.
μGAS1000 Trace Gas Reaction Evaluation System's software interface
The upper computer software of the μGAS1000 Trace Gas Reaction Evaluation System uses built-in calculation methods to read test data from the gas chromatograph. The software interface can directly display data such as gas production and reaction rate, and can preheat the system through the control heating module to effectively avoid valve sticking issues caused by solidification of vacuum grease. The new automated control design ensures compatibility of the μGAS1000 Trace Gas Reaction Evaluation System with any model of vacuum pump.

2. Gas circulation and automatic sampling module ensure high stability and accuracy of trace gas analysis
The gas circulation module of the μGAS1000 Trace Gas Reaction Evaluation System is mainly composed of a circulation pipeline and a gas circulation power source, with a volume of 230 mL for the circulation pipeline. The circulation pipeline is made of high borosilicate glass, and the narrow pipeline has a small inner diameter of 3 mm, resulting in low gas resistance. The gas circulation power source uses a passive magnetic drive fan pump, which has no risk of hydrogen explosion, does not generate interference from electrolysis water hydrogen, provides constant circulation power, and ensures that the gas pressure inside the system is above 3 kPa to guarantee good mixing effect. Gases such as H₂, O₂, CO₂ can be uniformly mixed within 10 minutes, and the linear regression of the calibration curve is >0.999. For the same concentration, continuous sampling four times, RSD <3%, achieving accuracy at the scientific level.

3. Various types of reactors can be selected to meet the needs of different reaction types
The μGAS1000 Trace Gas Reaction Evaluation System features a new reactor that can measure, record, and display the real-time reaction temperature during the reaction process by setting a thermocouple at the temperature measurement port. Its integrated design of the temperature control layer and the reactor chamber has high heat transfer efficiency and high experimental temperature control accuracy, effectively ensuring experimental repeatability.
