Industrial processes, such as thermal power generation and petrochemical production, involve emission of harmful gaseous chemicals and a growing number of companies are taking corporate environmental responsibility to take initiatives in monitoring, controlling and preventing pollutant emission. To enable timely and effective detection of gaseous pollutants in the industrial processes, we have developed a high-sensitive gas sensing and control system. It combining advanced laser spectroscopy technology (TDLAS and photoacoustic) and AI algorithm. The system provides the type, concentration, temperature and pressure of multiple gas components such as CO, NOx, NH3, SO2 in a complex environment in real time. It also gives feedback to the control terminal through wireless transmission.

Our system provides:

  • Simultaneous detection of multiple target gases generated by thermal power plants, industrial boilers and oil companies
  • Ultra-high sensitivity required in industrial processes (sub-ppb)
  • Real-time online sensing (response time < 3 s)

Handheld High-Resolution Short-Wave Infrared Spectrometer

Spectrometers are widely used in many different aspects, such as food and environmental inspection etc. However, it is necessary to have a portable and high-resolution spectrometer for real-time on-site inspection at remote farm or factory. CUHK team invented two new technologies, which broke the traditional boundary. We develop a handheld high-resolution short-wave infrared (SWIR) spectrometer […]
