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?
