| Study Title | Untargeted Discovery in Primary Metabolism: Collision Cross Section as a Molecular Descriptor in Ion Mobility Spectrometry |
| Study Type | Database Library |
| Study Summary | In this work we have established a collision cross section (CCS) library of primary metabolites based on analytical standards in the Mass Spectrometry Metabolite Library of Standards (MSMLS). Using a commercially available ion mobility-mass spectrometer (IM-MS, Agilent 6560), from the 554 unique compounds in the MSMLS plate library we obtained a total of 1246 CCS measurements over a wide range of biochemical classes and adduct types. Resulting data analysis showed that the curated CCS library provides broad molecular coverage of metabolic pathways and highlights intrinsic mass/mobility relationships for specific metabolite superclasses. The separation and characterization of isomeric metabolites were assessed as well as an investigation to determine the analytical separation efficiency in both the mass (m/z) and mobility (CCS/ΔCCS) dimension required for untargeted metabolomic analyses. To further demonstrate the analytical utility of CCS as an additional molecular descriptor, a well characterized biological sample of human plasma serum (NIST 1950) was examined by LC-IM-MS and a detailed analysis of carbohydrate isomers by ion mobility is presented. |
