Keeping Pace With PFAS Research

1 week ago | chromatographyonline.com | Alasdair Matheson

Chromatography plays a crucial role in the research and analysis of per- and polyfluoroalkyl substances (PFAS), a group of synthetic chemicals that have raised significant environmental and health concerns. Due to their unique chemical structure, PFAS are highly persistent in both the environment and living organisms, leading to their widespread presence in water, soil, and food (1).
Imre Molnár Named 2025 Tswiett-Nernst Award Laureate for Contributions to Separation Science

1 week ago | chromatographyonline.com | Kate Jones

Imre Molnár, president of the Molnár-Institute for Applied Chromatography, has been named one of two 2025 laureates of the Tswiett-Nernst European Award for outstanding achievement in the separation sciences. The award was established in 2010 by the European Society for Separation Sciences (EuSSS). On the dissolution of the EuSSS, the award was transferred to the Central European Group for Separation Sciences (CEGSS).
PFAS Researchers Call for Access to PFAS Reference Standards from Manufacturers

1 week ago | chromatographyonline.com | Alasdair Matheson

Scientific research into the impact of per- and polyfluoroalkyl substances (PFAS) on human health and the environment is hindered by limited access to high-purity reference standards, according to a team of researchers led by Xenia Trier, an associate professor from the University of Copenhagen, Denmark, and Stefan van Leeuwen, a senior scientist focusing on chemical pollutants at Wageningen University and Research, The Netherlands (1).
Miniaturized GC-MS Method for BVOC Analysis of Spanish Trees

1 week ago | chromatographyonline.com | Kate Jones

A team of scientists from the Analytical Chemistry Group (TESEA) at the University of Valladolid in Spain, has developed and validated a miniaturized, environmentally friendly method for profiling biogenic volatile organic compounds (BVOCs) from tree species using headspace solid-phase microextraction gas chromatography–quadrupole time-of-flight mass spectrometry (HS-SPME-GC–QTOF-MS). The study was published in the Journal of Chromatography Open (1).
A Matrix-Matched Semiquantification Method for PFAS in AFFF-Contaminated Soil

1 week ago | chromatographyonline.com | Alasdair Matheson

You recently published a manuscript paper entitled “Implementation of Matrix-Matched Semiquantification of PFAS in AFFF-Contaminated Soil” (1). What is matrix-matched semiquantification and why is semiquantification necessary? Semiquantification is used to estimate the concentration of chemical substances, such as per- and polyfluoroalkyl substances (PFAS), if analytical reference standards are not available.
High-Throughput Analysis of Cyanotoxins Using Automated Sample Preparation and SPE

2 weeks ago | chromatographyonline.com | Kate Jones

A team of scientists from Friedrich Schiller University Jena and Analytik Jena both in Jena, Germany, developed an automated sample preparation method to facilitate the detection of microcystins (MCs) and nodularin-R (Nod), two cyanotoxins commonly associated with harmful algal blooms (1). The approach features a fully automated solid-phase extraction (SPE) workflow in a 96-well plate format that integrates liquid chromatography–mass spectrometry (LC–MS) analysis.
The Current Challenges Mitigating PFAS

2 weeks ago | chromatographyonline.com | Will Wetzel

In part 5 of our conversation with Ralph Mead and his group, they talked about climate change and how it impacts carbon fluxes, describing the role of PFAS in these environments (1). In the final part of this interview, Mead and his group 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. Below is some of our conversation with Ralph Mead and his team.
The Role of PFAS Impacting Carbon Fluxes
