Analysis of Combinatorial Natural Products by HPLC and CE

University College London scientists recently created a new technique for selecting two-dimensional liquid chromatography (2D-LC) columns.

Scientists from the Henan Academy of Sciences recently developed a new technique for the determination of hydroxyl polycyclic aromatic hydrocarbons (OH-PAHs) from urine.

A new process for tracking targeted and non-targeted fluorinated residuals using liquid chromatography–high-resolution mass spectrometry (LC–HRMS) has been created.

An investigation into fluoroelastomer watch bands has revealed high levels of perfluorohexanoic acid (PFHxA), a short-chain per- and polyfluoroalkyl substance (PFAS). LCGC International spoke to Professor Graham Peaslee from the University of Notre Dame about his team’s study using liquid chromatography tandem mass spectrometry (LC–MS/MS) and PFHxA's potential for dermal absorption, and the subsequent environmental and health impacts.

Scientists from the National Institutes for Food and Drug Control have characterized antibody-drug conjugates (ADCs) using various mass spectrometry (MS)-based techniques.

“Forever chemicals” per- and polyfluoroalkyl substances (PFAS) have been found in smartwatch and fitness bands and analyzed using liquid chromatography tandem mass spectrometry (LC–MS/MS) and direct total oxidative precursor (dTOP) assay.
