Abstract
A small, transportable remote sensing, infrared air monitoring system (ROSE-FTIR) was developed for use in the workplace. A least squares fit method was presented that was designed to overcome the problem of background spectra contaminated by nonanalytes. The emphasis in this system is on simplicity and sensitivity for use over path lengths of up to 40 meters. A method was developed to overcome the effect of nonanalyte species present in the background spectrum on the quantitation of analytes in the sample spectrum. Results demonstrated that the instrument response was proportional to the beam path length under homogeneous concentration conditions. The results indicated that the ROSE-FTIR method is appropriate for the direct quantification of multicomponent mixtures of airborne gases and vapors at the parts per million concentration level. The application of software capable of qualitative analysis was also demonstrated. Studies were underway to assess the usefulness of the method for exposure assessment applications.
