FTIR spectroscopy has been shown to be a valuable tool in the analysis of complex gas phase mixtures, such as dilute vehicle exhaust. Regulated and non-regulated vehicle emissions have been routinely sampled and analyzed using prototype instrumentation developed in this laboratory, and in several other laboratories over the last decade. More recently, commercial versions of these FTIR analyzers have become available through several manufacturers. This paper reviews the data acquisition and processing techniques utilized by the FTIR analyzer developed in this laboratory. The statistical detection limits for 22 of the components analyzed by the system are presented. In addition, the linearity of the carbon monoxide (CO) analysis is demonstrated over several orders of magnitude. Experiments designed to study the effects of environmental parameters on the accuracy and the sensitivity to the system are also described.
