Paper Abstract

The use of FTIR spectroscopy, coupled with computer programs for species quantification, has now become reasonably well-established as a technique for quantitative analysis of gases and vapors. Classical Least Squares (CLS) fitting procedures allow rapid calculation of species concentrations even when there is severe overlap of spectral features. A major driving force in the development of FTIP-CLS procedures has has been in the field of auto exhaust emissions analysis. Other areas where the technique has found application are indoor and outdoor air pollution monitoring, general combustion product analysis, process control, and the analysis of trace species present in nearly pure gases. In almost all applications the analyses can be carried out by technicians not trained in spectroscopy once the species of interest have been identified and the wavenumber regions for analysis have been established.
