Using Chromatography to Explore Fluorescent Bioactive Compounds in the Coelomic Fluid of Earthworms
A study aiming to identify fluorescent bioactive compounds in the coelomic fluid of earthworms, as well as to investigate their structural and functional characteristics for possible use in biomedical applications, utilized a variety of chromatographic techniques.
Assessing Thorium-Peptide Interactions Using Hydrophilic Interaction Liquid Chromatography
February 4th 2025Paris-Saclay University scientists used hydrophilic interaction liquid chromatography (HILIC) coupled to electrospray ionization mass spectrometry (ESI-MS) and inductively coupled plasma mass spectrometry (ICP-MS) to assess thorium’s interaction with peptides.
Evaluating Dissolved Organic Matter with GPC and Spectroscopy
Gel permeation chromatography, three-dimensional excitation-emission matrix fluorescence spectroscopy, and UV-visible spectroscopy was utilized to assess road runoff passed through a filter filled with sludge from drinking water treatment plants to evaluate its capacity for removing dissolved organic matter (DOM).
Assessing Metal-Induced Glycation in French Fries with LC-MS/MS
A recent study described develops methods for synthesizing and quantifying metal-induced glycation products, particularly in French fries, with phytic acid as a natural chelating agent (NCA). LCGC International spoke to Makan Golizeh, corresponding author of the paper inspired by this research, about the study and the team’s use of liquid chromatography-tandem mass spectrometry (LC–MS/MS) in their research.
Identifying Multidimensional Characteristics of PFAS Using LC-DTIMS-HRMS
A recent study used a liquid chromatography-drift tube ion mobility spectrometry-high resolution mass spectrometry (LC-DTIMS-HRMS) platform to contribute to characterizations of 175 per-and polyfluoroalkyl substances (PFAS) with authentic standards in a multidimensional manner.
PFAS Dermal Absorption: An Overview of Science and Regulation
Per- and polyfluoroalkyl substances (PFAS) often make headlines as health agencies worldwide work to regulate their use. While most restrictions focus on PFAS in drinking water, the primary exposure pathway, scientists are increasingly investigating alternative routes, such as dermal absorption from cosmetics, sunscreens, and other everyday products.
