Petroleomic Characterization using an Ion Mobility-Orbitrap Platform (ASMS 2016)

<p>Ion mobility spectrometry (IMS) is a fast gas-phase separation technique that separates ions in part based upon their shape. Different chemical classes form shape-related ‘trend lines’ in the 2D drift time-m/z chromatogram. These trend lines can be utilized as a quick diagnostic for chemical classes, and hence information that augments that from mass spectrometry. Herein we present a new IMS-Orbitrap platform that couples the benefits of drift-tube IMS with a high mass resolution Orbitrap MS. The new platform was utilized to analyze and profile an array of petroleum products, and highlights the utility of the IMS -Orbitrap platform for analysis of highly chemically complex substances.</p
