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.

The Use of Pyrolysis/GCMS and Newly Developed Libraries to assist in Characterizing Complex Polymeric SamplesPoster
Pyrolysis-GC/MS is an effective tool in introducing and analyzing polymers. But since the polymer must be broken down to volatile segments in order to be sent to the GC, identification by the Mass Spec does not look at the original polymer, but only the fragments. This poster will look at a unique library designed to work with the existing NIST library, however contains averaged spectra of pyrolyzed polymers so it can be used to directly identify the original polymer sample.READ MORE
