Poster Information
Abstract: Petroleum is the most complex matrix in nature, constituted by many thousands of compounds, and presents an analytical challenge. As the world's remaining deposits of petroleum become heavier, it's important to understand the chemical nature of heavy crude oil and its fractions. The analysis of high-boiling point constituents adds a new dimension for the complete characterization of crude oil. In this study we evaluated the use of a pyrolysis probe coupled to gas chromatography high resolution time-of-flight mass spectrometry (Py-HC-HRTOFMS) for the characterization of crude oils and asphaltene fractions.Summary: Py-GC-HRTOFMS analysis with high resolution and high mass accuracy is crucial for identification of crude oil and asphaltene pyrolysis products by unequivocal chemical formula assignment, with enhancement of sensitivity and selectivity. Analysis of petroleum and respective asphaltene fractions from diverse geographical origins are under evaluation as part of future work.References: Leco CorporationReport abuse »
