The monitoring of fluid evaporation from within fiber-optic micro-cells is proposed and demonstrated. The evaporation process is accompanied by a pronounced temporary attenuation in the transmission of light through the micro-cell, by as much as 50 dB. The temporal attenuation profiles observed for acetone, ethanol and hexane are distinctly different. Temporal attenuation measurements can therefore allow for the identification of fluids based on their physical properties, rather than their refractive indices. The evaporation of fluid mixtures is monitored as well.
