Applications of Ion Mobility-Mass Spectrometry in Lipid Profiling and Imaging

Lipidomics, the comprehensive analysis of lipids within a biological system, continues to gain popularity as it offers insight into metabolic phenotype and underlying mechanisms of many diseases and conditions. However, most lipid species occupy a narrow mass range, which presents challenges to lipid identification.
In recent years, liquid chromatography coupled to ion mobility-mass spectrometry (LC-IM-MS) for lipidomics has shown advantages in lipid identification. In particular, collision cross section (CCS) obtained from the IM measurements represents a physical property that can be used to enhance the confidence of lipid identification.
What You Will Discover:
- Recent progress in mapping the lipid CCS-mass landscape
- Establishment of experimental and theoretical lipid CCS databases
- Application of IM-MS in profiling and MS imaging of lipids
