In the final part of this interview, Ralph Mead and his group at the University of North Carolina, Wilmington, discuss the biggest challenges in mitigating the effects of PFAS right now. Here’s the final part of our conversation with the Mead Group at UNC Wilmington.

In part 5 of this interview, Ralph Mead and his group at the University of North Carolina, Wilmington talk about climate change and how it impacts carbon fluxes, describing the role of PFAS in these environments.

In the below video segment, we asked Ralph Mead and his team at the University of North Carolina, Wilmington, about the information gaps in understanding the transport of PFAS.

A multidimensional liquid chromatography (LC)-based technique was created to help profile antioxidant metabolites in onion leaf extracts.

In part three of this interview, they discussed the interactions between bacterial communities and replacement PFAS materials. Here's part three of our conversation with the Mead Group at UNC Wilmington.

With green chemistry becoming more standardized, Leena Pitkänen of Aalto University analyzed how useful size-exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4) could be in characterizing plant polysaccharides.

In part 2, Ralph Mead and his team explain the challenges of characterizing and quantifying PFAS in environmental samples.

The Mead Group at UNC Wilmington studies the occurrence and transport PFAS in wet and dry depositions, tracing their sources to inform regulators. In the first part of our interview, we spoke with Mead and several members of his team about the work they do for the North Carolina PFAS Testing Network and learn more about the network.

Researchers from KU Leuven explored two-dimensional liquid chromatography (2D-LC)’s application to profile micropollutants in wastewater.

In this edition of the LCGC Blog, Amber Hupp of the College of the Holy Cross reflects on her childhood and talks about her journey recreating the scents from that long past.

Microplastics and nanoplastics have been identified in the lungs of wild birds using laser direct infrared (LDIR) chemical imaging and pyrolysis gas chromatography–mass spectrometry (Py-GC–MS), in the first multi-species evidence of these plastics in bird lungs.

David Megson from Manchester Metropolitan University in Manchester, UK, spoke to LCGC International about the latest developments in non-targeted analysis (NTA) of per- and polyfluoroalkyl substances (PFAS) in environmental matrices based on a recent systematic review paper he has collaboratively published (1).

Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.

Using pyrolysis-gas chromatography and mass spectrometry, scientists from Fudan University and the Putuo District Center for Disease Control and Prevention detected and quantified microplastics in newborn stool samples.

In this final part of our interview with Females in Mass Spectrometry (FeMS) Empowerment Award Winner Josephine Ouma, we discuss her future research efforts and what Women's History Month means to her.

In this second part of our interview with Females in Mass Spectrometry (FeMS) Empowerment Award Winner Josephine Ouma, we discuss her experience with mass spectrometry and how FeMS has impacted her life.

Emanuela Gionfriddo and Madison Williams from University at Buffalo, the State University of New York, NY, USA discuss the important role that solid-phase microextraction (SPME) techniques with gas chromatography mass spectrometry (GC–MS) can play in the analysis of per- and polyfluoroalkyl substances (PFAS).

In this first part of our interview with Females in Mass Spectrometry (FeMS) Empowerment Award Winner Josephine Ouma, we discuss her PhD research and what inspired her to join FeMS.
