The full characterization of petroleum compounds including separation of isomers is one of the most challenging tasks in chemical analysis. 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 on-demand presentation describes the advantages that IM-MS offer for petroleum analysis, including isomeric resolution. Hosted by C&E News.

Particpants Will Learn:

  • The benefits and complementary information that ion mobility offers to petroleum analysis.
  •  How software for automated elemental composition assignment (PetroOrg) can 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.
