Abstract
Infrared spectroscopy has been used successfully for the determination of carbon dioxide and some solvents in diving air, but has been limited by the lack of sensitivity in a single scan to detect the low levels necessary for most components. However, the recent availability of the Fourier Transform Infrared Spectrometer (FT-IR) with its inherent better light through-put and multiple scan advantages has improved the sensitivity of infrared spectrometers substantially. The advantages of infrared spectroscopy over other analytical methods include the ability to look for all components in the gas mixture simultaneously, including unexpected components. The advent of computer data handling capabilities for integrating and comparing infrared spectra has also increased the utility of the technique.
