Liquid chromatography–tandem mass spectrometry (LC–MS/MS) reveals distinct sphingolipid patterns in anorexia and obesity.
A single drop of blood represents a complex mixture of biological compounds including phospholipids, proteins, and salts. Frederic Lynen of Ghent University in Belgium discusses the possibilities of a HILIC-based SPE approach to remove phospholipids from blood samples, its applicability to other organic molecules, and how it benefits the chromatographer in practice.
