A new method has been created for determining N-nitrosamines (NAs) in pharmaceutical preparations using liquid chromatography with tandem mass spectrometry.

University of Turin scientists developed a UHPLC–PDA-MS/MS-based method for quantifying plant-specialized metabolites for determining the quality of medicinal and aromatic plants.

Ion chromatography can be utilized in various ways to analyze halogens and similar substances within inorganic matrices.

New methods have been developed to determine polar emerging contaminants with hydrophilic interaction liquid chromatography (HILIC) techniques.

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.

We recently published a three-part interview with Chris Reddy. Here, we provide the full text transcript of the conversation, which includes some additional insights not presented in the video interview.

In a continuation of our Inside the Laboratory interview with Chris Reddy, we asked him about the recent documentary, “Out of Plain Sight,” that featured him and his team’s research.

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 Nanjing University recently developed a new solid-phase microextraction (SPME)-based system for detecting nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) in aquatic environments.

In the second part of this edition of “Inside the Laboratory,” Christopher Reddy of Wood Hole Oceanographic Institution discusses why comprehensive two-dimensional gas chromatography is the optimal technique for investigating complex mixtures of organic chemicals in the environment.

“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.

In this edition of “Inside the Laboratory,” Christopher Reddy of Wood Hole Oceanographic Institution discusses his laboratory’s work investigating oil spills and uncovering dichlorodiphenyltrichloroethane (DDT) deposits on the ocean floor. This interview is part one of three of our conversation with Reddy.
