Combining OFCEAS Spectroscopy and Low Pressure Sampling for Low Concentration Measurements

Jul 26 2023

At ILM's Air Quality and Emissions (AQE) event, Étienne Smith of Durag Group shared a unique combination of OFCEAS (optical feedback cavity enhanced absorption) spectroscopy and low pressure sampling to provide atmospheric readings. This talk covers:

  • What is OFCEAS spectroscopy?
  • What is low pressure sampling?
  • The analytical possibilities of this combined method
  • Selected applications of the method
  • Does this method require calibration?
  • Why haven't the method's NO limit-values been brought down further?
