Abstract A method for measuring ambient levels of nonmethane hydrocarbons (NMHCs) has been developed and an instrument based on that method has been built. The instrument consists of a sample conditioner and an optical CO2-CO monitor. In the sample conditioner ambient air is scrubbed of CO2 and H2O and any NMHCs and CO present are catalytically oxidized to CO2. The CO2-CO monitor measures both the original CO present in the air as well as the CO2 resulting from conversion of NMHCs and the CO. The CO2 channel of the CO2-CO monitor measures the concentration of the CO2 produced, which is directly related to the concentration of NMHC.
