Calibration problems connected with the determination of C20-C44 petroleum hydrocarbons by gas chromatography – flame ionization detection (GC-FID) and IR spectrometric methods were studied in this paper. It has been found that the mass responses and mass response factors of FID determined by capillary GC-FID as well as by IR spectrometry, at wave number 2959 and 2924 cm-1, of high boiling petroleum...
