Combining OFCEAS Spectroscopy and Low Pressure Sampling for Low Concentration Measurements

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?
