Issue Date: | 30-Jan-2004 | Publisher: | Elsevier | Citation: | Journal of Chromatography A 1025(1): 133-138 (2004) | Abstract: | A rapid and simple fractionation procedure using solid-phase extraction (SPE) cartridges was developed for an accurate determination of aliphatic and polycyclic aromatic hydrocarbons in petroleum residues and further application in chemical fingerprinting of oil spills by gas chromatography–mass spectrometry (GC–MS). Among the adsorbents evaluated, SiO2/C3---CN exhibited the best selectivity, providing, by elution with n-hexane (4 ml) and n-hexane–CH2Cl2 (1:1) (5 ml), two well-resolved aliphatic and aromatic hydrocarbon fractions, with recoveries of 97±7.2 and 99.7±13.9%, respectively. The SPE fractionation procedure was compared with the conventional silica–alumina adsorption chromatography showing similar results but practical advantages in terms of reproducibility, analysis time, solvent reduction and cost. Moreover, is particularly suitable for routine analysis with a high sample throughput. The developed methodology was tested in the characterization of fuel-oil samples collected along the Spanish north-west coast, after the Prestige oil spill accident. | Description: | 6 pages, 5 tables.-- PMID: 14753680 [PubMed].-- Available online Dec 4, 2003.-- Issue title: "ExTech 2003 - The 5th International Symposium on Advances in Extraction Technologies " (St. Pete Beach, Florida, USA, Mar 5-7, 2003). | Publisher version (URL): | http://dx.doi.org/10.1016/j.chroma.2003.10.080 | URI: | http://hdl.handle.net/10261/16659 | DOI: | 10.1016/j.chroma.2003.10.080 | ISSN: | 0021-9673 | E-ISSN: | 1873-3778 |
