The Fourier transform infrared spectrophotometry (FTIR) used for the direct analysis of gas and vapor contaminants of workplace air was examined. The evaluation was conducted using results obtained from the FTIR for the analysis of samples of carbon-disulfide (CS2) eluates containing trichloroethylene (79016) (TCE) and Freon-113 (76131) from charcoal air sampling tubes. The results were compared to those obtained on gas chromatographic analysis. The FTIR spectrum of CS2 vapor examined demonstrated several strong peaks, two of which were observed to overlap with TCE. Freon-113 was also noted to overlap with TCE at one of these same peaks. However, the FTIR yielded accurate results without regard to the presence of Freon-113. The authors suggest that additional evaluations be conducted to determine the questions of the speed and cost of this method, and the usefulness of the technique for the identification of unknown constituents in the air samples.
