| Abstract | A Fourier transform infrared remote sensor (FTIR-RS) was used to measure chemical emissions at the Shaver's Farm Superfund site in northwestern Georgia. The system was bistatic with a source/receiver at one end of a 250 m path and a retroreflector at the other end. The source/receiver was a Nicolet Model 730 FTIR system coupled to a telescope with the appropriate transfer optics. The average concentrations of target gases along the path are inferred by matching field spectra with reference spectra of precisely measured quantities of the target gases. Measurements indicated that benzonitrile and benzaldehyde concentrations at the site were lower than the FTIR-RS detection limits of 70 and 16 ppm-m, respectively. Background IR radiation was successfully eliminated by modulating the IR beam before it was transmitted along the path. Quality assurance measurements to establish the precision and accuracy of known gas burdens (ppm-m) were carried out using a 15-cm cell containing high concentrations of several gases. |
