Description:
As part of a Superfund Innovative Technology Evaluation (SITE) field program, a Fourier transform infrared (FTIR) spectrometer vas used to make open path measurements of volatile organic compounds in the New Castle, Delaware, area. he SITE program requires that new technologies be compared with more mature measurement techniques. n this case, a canister-based sampling and analytical methodology was chosen to compare with the FTIR measurements. hole air samples were collected in the canisters as they were repeatedly transported along the open measurement path of the FTIR spectrometer. TIR spectra were co-added for 32-min sampling intervals. Conclusions were: (1) that the FTIR system as it is currently configured can be used as a reliable monitoring instrument when the concentrations are greater than about 50 ppbv; (2) that transporting the canisters along the path is a viable technique for comparing long-path and point-sampler measurements.
