WebH. Alex Brown, in Biochemistry of Lipids, Lipoproteins and Membranes (Sixth Edition), 2016. 3.3.4 High-Performance Liquid Chromatography. HPLC is a chromatographic technique similar to GC that involves the migration of a lipid mixture through a column containing a stationary phase. However, in HPLC the mobile phase is a liquid instead of a gas.
