Determination of Polymerized Triaclyglycerides by High Pressure Liquid Chromatography and Corona Veo Charged Aerosol Detector

Combining silicon micro-nanofabrication technology to create perfectly ordered separation beds on a silicon chip, i.e. micro-pillar array columns (µPACs) is a powerful innovation in liquid chromatography. This article discusses the numerous possibilities of micro-nanofabrication in the future of analytical chemistry in life science, covering sample preparation, separation science, and detection technologies.

The article discusses advancements in two-dimensional liquid and gas chromatography (LC×LC and GC×GC) to address the challenges of analyzing complex samples in non-target analysis.

The 54th International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC 2025) will be held from Sunday through Thursday, 15–19 June, 2025, in Bruges, Belgium.

A joint study between the University of Tennessee (Knoxville, Tennessee) and the University of Pennsylvania School of Veterinary Medicine (Philadelphia, Pennsylvania) compared directly measured vitamin K1 (vitK1) concentrations in healthy dogs and dogs with chronic enteropathy (CE) using liquid chromatography tandem mass spectrometry (LC–MS/MS); they also investigated whether supplementation of vitK1 in dogs with CE would significantly increase vitK1 concentrations.
