LIPID MAPS® Lipidomic Ion Mobility Database

Overview of Interfaces
Search

The Lipidomic Ion Mobility database was developed in collaboration with the McLean research group at Vanderbilt University, Nashville, TN who have generated a repository (The Unified Compendium) of > 3800 experimentally acquired CCS values obtained from traceable molecular standards and measured with drift tube-mass spectrometers.

The initial database was created by mapping a subset of 835 lipid measurements to the LIPID MAPS® classification system and contains representatives from 7 of the 8 major lipid categories. We have recently expanded the database to include data provided by the Griffin lab at the University of Cambridge, UK, who aquired 47 Fatty Acids, for which a total of 268 conformers could be detected.

The Lipidomic Ion Mobility database can be searched by lipid name and filtered by LIPID MAPS® lipid category.
