Abstract

Recently, infrared transmitting optical fibers have been employed for remote spectral analysis of processes such as composite curing and polymerization of polyurethane. By imbedding the fiber in the sample, spectra can be obtained by measuring the attenuation of the evanescent wave that penetrates into the sample. This method, fiber optic attenuated total reflectance (FO/ATR), provides a minimally invasive technique for probing the chemistry occurring inside the sample during processing. The purpose of this work is to extend FO/ATR to the analysis of harsh liquid process streams that are difficult to monitor using other techniques.
