Innovative method of direct determination of the content of paraffins, naphthenes, aromatics and sulfur compounds by capillary high-resolution gas chromatography
Based on determination of individual Hydrocarbon (paraffins, naphthenes, aromatics) and Sulphur components of fuels and their mixture on the thin bonded of absorber (the stationary phase is a 100-metre silica capillary column, containing 0.5μm film thickness of bonded dimethylpolysiloxane phase) by means of the selective solvents (mobile phase) combined with technique of ionization of separated compounds by Flame Ionization Detector (FID) and Sulphur Chemiluminescence Detector (SCD).
