OVERVIEW

Petroleomics has been called the next grand challenge for chemical analysis. The full characterization of petroleum compounds, including isomer separation, is a daunting technical task. Ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) resolves and identifies the elemental compositions of all compounds present in complex crude oil samples. However, isomers cannot be directly resolved by mass measurement alone. Ion mobility mass spectrometry (IM-MS) offers a fast and powerful tool to complement FT-ICR MS analysis of petroleum samples, as it can access compounds spanning a wide range of polarity/volatility and separation occurs on a millisecond timescale. This presentation will discuss the myriad advantages that IM-MS offers for petroleum analysis, including isomeric resolution.

KEY LEARNING OBJECTIVES:

- The benefits and complementary information that ion mobility offers to petroleum analysis.

- How software for automated elemental composition assignment (PetroOrg) enhance the interpretation of petroleum ion mobility mass spectrometry data.

- How to benefit from the high resolving power of the TOF mass analyzer and how to overcome its limitations for the analysis of highly complex petroleum samples.
