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.application/pdfenIn CopyrightChalcogenide glass fiberRemote IR spectroscopyEvanescent absorptionFiber optic sensorsOptical fibersSensorsArticle - Refereedhttp://www.opticsinfobase.org/ao/abstract.cfm?URI=ao-33-27-6315https://doi.org/10.1364/AO.33.006315
