WebHydrophilic interaction liquid chromatography (HILIC) is an emerging MS-compatible separation technique that retains polar compounds through multiple retention mechanisms (1). Its inverse retention characteristics compared to reversed-phase liquid chromatography (LC) offers an advantage in separation of polar metabolites (2). WebHILIC has been referenced as one of possible approaches. However, there is a lack of experimental evidence in scientific literature so far. Methodology: Matrix effects were …
