摘要：
Micro-solid-phase extraction is reported for the preparation of Bohai crude oil for the determination of hydrocarbons by gas chromatography-mass spectrometry. The operational parameters were optimized. Micro-solid-phase extraction provided higher quantities of low-molecular weight components than conventional liquid chromatography. The concentrations of high-molecular weight n-alkanes, polycyclic aromatic hydrocarbons, and their alkylated homologs obtained were comparable by micro-solid-phase extraction and liquid chromatography. The diagnostic ratios also indicated that there were no significant differences between these methods. Therefore, micro-solid-phase extraction with gas chromatography-mass spectrometry is recommended for the characterization of spilled oil.
