AOTF-NIR Determination of % Ethanol and Menthol % in a Spray Solution

A Brimrose AOTF-NIR Luminar spectrometer was used to scan spectral data on mixtures of ethanol and menthol in varying proportions. Regression models were created for both ethanol and menthol and these models were used to do predictions on the mixtures. The predictions were very accurate and proved that the Brimrose AOTF-NIR Luminar spectrometer can measure % ethanol and % menthol in a mixed solution.
