Analysis of Tall Oil Fatty Acids Using AOTF-NIR Spectroscopy

A Brimrose AOTF-NIR Luminar spectrometer was used to scan spectral data on samples of tall oil fatty acid with varying amounts of rosin acid and acid numbers. Unknown samples were predicted using the calibration model and the results proved that the Brimrose AOTF-NIR Luminar spectrometer can accurately predict rosin acid and acid number in tall oil fatty acid.
