Quantitative Infrared Spectroscopic Measurements of Mixtures without External Calibration

Volume 33, Number 4 (Aug. 1979) Page 349-350

Koenig, Jack L.; Kormos, Donald


A general spectroscopic method for the analysis of mixtures that does not require external calibration has been developed. The method is based on the obtaining of absorbance ratio spectra and the determination of a concentration ratio at frequencies unique to each component. The method is applied to mixtures hexane and cyclohexane.
