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.
