Paper Abstract

Spectral analysis of human blood serum was carried out by fiberoptic evanescent wave spectroscopy (FEWS) and Fourier transform infra red (FTIR) spectrometer, with a silver- halide fiber as the sensing element. The concentrations of three blood components were predicted simultaneously using neural network (NN) models. In order to overcome the problem of fiber deterioration caused by interaction with serum salts, the fiber was coated with a plastic layer. The coating was tested and found to provide excellent protection to the fiber placed in a 3.5% salt solution. This method may be used for in-situ real time and long-lasting measurements.
