Lipid Species Imaging

Desorption ionization and imaging MS

  • this section describes guidelines for various desorption ionization and imaging MS techniques, including.:
    • matrix-assisted laser desorption/ionization, MALDI
    • secondary ion mass spectrometry, SIMS
    • desorption ESI
  • lipid species identification is based on principles discussed for shotgun lipidomics
  • type of lipid ions generated in the ionization process should be evaluated
  • additional evidence from other methods should be used to justify the correct lipid species identification
