Jerome Workman Jr.

A pioneer of FT-ICR Mass Spectrometry, Alan G. Marshall (1944–2025), is best known for co-inventing Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), a transformative technique that enabled ultrahigh-resolution analysis of complex mixtures. Over a career spanning more than five decades at institutions like the University of British Columbia, The Ohio State University, and Florida State University, he published over 650 peer-reviewed papers and mentored more than 150 scientists. Marshall’s work profoundly impacted fields ranging from astrobiology to petroleomics and earned him numerous prestigious awards and fellowships. Revered for his intellect, mentorship, and dedication to science, he leaves behind a legacy that continues to shape modern mass spectrometry.

LCGC’s Senior Technical Editor Jerome Workman, Jr examines the history of chemicals classified as POP, or persistent organic pollutants, and PFAS, or per- and polyfluoroalkyl substances, then reviews their place in today's environment and assesses risks for the future.

We interviewed an AI program (ChatGPT) for LCGC North America asking questions about AI and its role in various applications for separation science to include data analysis, and high performance liquid chromatography (HPLC), hydrophilic-interaction chromatography (HILIC), reversed-phase liquid chromatography (RPLC), liquid chromatography–mass spectrometry (LC–MS), gas chromatography–mass spectrometry (GC–MS), high resolution mass spectrometry (HRIM–MS), high resolution tandem mass spectrometry (HRMS/MS), and related topics.

The monitoring of per- and polyfluoroalkyl substances (PFAS) into food is an important environmental and health concern. Raquel Sendón García, PhD, is a Faculty Member in the Department of Analytical Chemistry of Nutrition and Food Science, and a Faculty of Pharmacy member at the University of Santiago de Compostela in Spain. She has been performing research on food contamination and the presence of potentially harmful chemicals in foods for some time. We recently spoke to her about her work using GC–MS and other analytical techniques to analyze PFAS migration into food from packaging materials.

As our knowledge about PFAS in food continues to develop, and regulations evolve, we must continue to refine our analytical methods.
