Trapped ion mobility spectrometry and PASEF enable in-depth lipidomics from minimal sample amounts

, 2020
A comprehensive characterization of the lipidome from limited starting material remains very challenging. Here we report a high-sensitivity lipidomics workflow based on nanoflow liquid chromatography and trapped ion mobility spectrometry (TIMS).
