The EAS Award for Outstanding Achievements in the Fields of Analytical Chemistry was presented to Linda B. McGown at EAS on 14 November. McGown is the William Weightman Walker professor of the Department of Chemistry and Chemical Biology at Rensselaer Polytechnic Institute (Troy, New York, USA). In her early career, McGown exploited the capabilities of frequency-domain fluorescence lifetime spectroscopy to create multidimensional data formats to characterize and classify complex samples such as human serum, humic substances, and petrolatums. She then integrated fluorescence lifetime detection into separation techniques. In the 1990s, McGown took an interest in aptamers. Her current work focuses on genomeâinspired approaches to aptamer discovery to complement combinatorial methods, to explore a naturally evolved sequence space often underrepresented in combinatorial libraries. McGown has been a Fellow of the American Association for the Advancement of Science since 200 and received the New York Section of the Society for Applied Spectroscopy Gold Medal Award in 2004. She was included in The Future of Women in Chemistry and Science programme in honour of UNESCO’s declaring 2011 the International Year of Chemistry. She was one of “60 exemplary thinkers” who spoke about how to expand women’s leadership in the sciences, across all disciplines and sectors.
An LC–HRMS Method for Separation and Identification of Hemoglobin Variant Subunits
March 6th 2025Researchers from Stanford University’s School of Medicine and Stanford Health Care report the development of a liquid chromatography high-resolution mass spectrometry (LC–HRMS) method for identifying hemoglobin (Hb) variants. The method can effectively separate several pairs of normal and variant Hb subunits with mass shifts of less than 1 Da and accurately identify them in intact-protein and top-down analyses.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
