Abstract
A fiber-optic coupled FT-NIR spectrometer was used to measure the NIR spectra of a series of extruder samples in the laboratory. The chemical composition of different sample sets were predicted from their NIR spectra using multivariate statistical methods. The instrument was also successfully used to obtain the NIR spectra of similar materials on-line at an extruder exit port.
