    Infrared Evanescent-Absorption Spectroscopy with Chalcogenide Glass-Fibers
    Sanghera, J. S.; Kung, F. H.; Pureza, P. C.; Nguyen, V. Q.; Miklos, R. E.; Aggarwal, I. D. (Optical Society of America, 1994-01-01)
    We have used telluride glass fibers fabricated in house to measure the evanescent-absorption spectra of water, methanol, ethanol, isopropanol, acetone, ethanoic acid, hexane, and chloroform. Furthermore, detection limits of less than 2 vol. % solute were obtained for mixtures of water and methanol, ethanol, isopropanol, acetone, and ethanoic acid. Techniques to reduce the detection limits are discussed.
