On January 1, 2010, the U.S. Environmental Protection Agency required
large emitters of heat-trapping emissions to begin collecting greenhouse gas
data under a new reporting system. Nitrous oxide (N2O) Carbon
dioxide (CO2), methane (CH4) and are considered the main
greenhouse gases in the Earth's atmosphere. These gases absorb strongly in the
infrared trapping heat in the atmosphere and affecting the temperature on the
Earth. These gases have been measured using expensive long path infrared
analyzers or complex gas chromatography using as many as three detectors and
three valves. We developed a far UV absorbance detector (FUV 1) that we will
apply to analysis of all three gases. It will just require a concentrator to
detect ppb levels of these gases. The FUV detector recently has been improved
so that it can detect low ppm levels of these compounds. We had developed a
concentrator for N2O that could also be used for CO2 and
plan some additional changes to the FUV to improve its sensitivity to CH4.
