Excerpt from News Briefs, Vol. 99: Journal of Research of the National Institute of Standards and Technology; March-April 1994
In their quest to build cleaner cars, automobile manufacturers require advanced measurement methods to precisely monitor what goes in and comes out of a car’s engine. A new, nist-devel oped automated microwave Spectrometer that can analyze trace gases quickly and accurately with very high sensitivity may fit the bill. Among the instru ment’s potential applications are monitoring auto exhaust, factory emissions and industrial processes. The nist device can accurately measure gases in concentrations as low as 10 parts per billion.
