Such analyses are important for technical diagnostics as well as specific sample characteristics. The sample preparation together with an efficient sample introduction allowed a fast quantification of the analytes using calibration curves prepared with analyte organic standards. Trace element occurrences, forms, distributions are examined as well as their implications in terms of reservoir geochemistry, oil refining and environment.展开更多
To extract pure bitumen, the bitumen from Bayan-Erkhet, Zuunbayan and Ukhaa was prepared into small particles of 0.2 - 0.5 cm and then it was infused with chloroform in the Soxhlet apparatus [1] [2].

The physical-mechanical properties were identified after the solvent was extracted from the chloroform infused bitumen through the vacuum evaporation method. The characteristics of the debris without bitumen or the remains after the infusion were examined in details. The hydrocarbon content of the bitumen was identified with the device: Agilent 7890-5975c Gas chromatography mass spectrometer.展开更多
