Detecting greenhouse gases in the atmosphere could soon become far easier with the help of an innovative technique developed by a team at the National Institute of Standards and Technology (NIST), where scientists have overcome an issue preventing the effective use of lasers to rapidly scan samples.

The team says the technique also could work for other jobs that require gas detection, including the search for hidden explosives, and monitoring chemical processes in industry and the environment. The team’s paper, “Frequency-Agile, Rapid Scanning Spectroscopy,” was published April 28, 2013, in Nature Photonics.

Another way to skin this cat
A Mass Spectrometer is already at work doing just this type of field detection. The Owlstone device is a dime sized FAIMS gas detector that can detect almost any ionizable molecule. Visit this site: http://www.owlstonenanotech.com/products to see the various implementations available and learn of the new applications under development. The ARFCAM chemical agent monitor specifically monitors ambient air for selectable contaminants and can be programmed to detect multiple targets.
The sensor is being made for hand held devices and has multiple applications in process control, threat detection, contamination detection among other developing opportunities.
The quality management industry will be well served to learn about this new, ground breaking technology.
