项目名称:Gas Sensor for Ammonia, Carbon Dioxide, and Water (氨、二氧化碳、水的气敏元件)
编号: 01-032
类别: Sensors/Optical Sensors

项目描述:
Researchers from Prof. Ronald Hanson’s laboratory have developed a sensitive, patented gas sensor that uses diode lasers to simultaneously detect ammonia, carbon dioxide, and water vapor. This sensor is particularly useful for measuring trace amounts (ppm levels) of ammonia without interference from typical background species. Compared to previous gas detection instruments, this technology is rapid, versatile, and inexpensive. The sensor system can be used in a variety of monitoring applications, including environmental, semiconductor clean room, vehicle exhaust, and breath analysis.
Stage of Research
The inventors have used this technology as a portable, automated sensor to achieve minimum detection of 0.25ppm for ammonia and 40ppm for carbon dioxide in bioreactor vent gases.
适用:
Sensors - particularly for detecting trace ammonia levels, with applications in:
  • environmental and air quality monitoring
  • semiconductor cleanroom monitoring
  • car exhaust monitoring
  • medical breath analysis
优势:
  • Rapid, specific multi-species monitoring of ammonia, CO2, and H2O without interference from typical background species
  • Sensitive: measures ammonia at ppm levels or below in the presence of common atmospheric interferences
  • Inexpensive to produce: affordable and commercially available semiconductor diode lasers
  • Versatile measuring capability:
   o incorporate with fiber optics for remote detection or detection at multiple locations
   o multiplexing other lasers for detecting multiple species or parameters simultaneously
