Abstract (in english)
   To determine etheric oxygen in chemically and physically heterogeneous maceral fractions of bituminous coals, 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 was demonstrated by the determination of etheric oxygen in 26 standards and 14 samples of coal maceral fractions. 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
