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.
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.
The new benchtop encloser can be equipped with interchangeable onboard air filtration options to protect samples from contamination or reduce user exposure to harmful chemical gases.
Researchers have developed a method employing high performance liquid chromatography with ultraviolet detection (HPLC-UV) to determine vitamin D3 in food (even in the presence of vitamin D2, and with a specific focus on egg yolk) in a cost-effective and quantitative manner.
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.
Waters Corporation recently announced two new columns to their MaxPeak Premier Reversed-Phase Column portfolio during the conference in Washington, DC.
