Electrochemical Strategies in ESI-MS for Lipid Analysis
Description
Lipids play a vital role in maintaining cellular functions. Altered lipid metabolism is currently considered a hallmark of many diseases, which highlights the importance of the characterization of lipid composition in understanding, diagnosing, and treating pathologies. Discrimination of isomeric species is challenging in lipidomics. In this talk, I will introduce the microdroplet electrochemical methods capable of resolving different types of isomers commonly encountered in lipid samples using electrospray ionization mass spectrometry. The methods take advantage of the voltage-controlled and dramatically accelerated electrochemical derivatization of lipid isomers in microdroplets to achieve structural elucidation. Applications of the electrochemical mass spectrometry methods in real sample analysis will also be included.
