Abstract: To determine etheric/hydroxyl oxygen in chemically and physically heterogeneous materials the method combining diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) with the advanced statistic partial least-squares method (PLS) was developed. The DRIFTS-PLS method yields exact and accurate results, as it is demonstrated by the determination of etheric/hydroxyl oxygen in 40 samples. Quickness is an important feature of the method, as it reduces the duration of the determination from tens of hours to several minutes. For this reason, the method is suitable for analyses of large sets of heterogeneous samples.
