The accuracy of the simultaneous multielement determination was verified by the flow-injection-ICP MS analysis of certified reference materials (wear-metals in lubricating oils: SRM 1084a and SRM 1085b). The method allowed the acquisition of chromatograms with high sensitivity competitive existing methods, showing element- and sample origin-dependent morphology. © 2010 The Royal Society of Chemistry.Mahidol UniversityChemistryMultielement molecular size fractionation in crude oil and oil residue by size exclusion microchromatography with high resolution inductively coupled plasma mass spectrometric detection (HR ICP MS)ArticleSCOPUS10.1039/c0ja00076k
