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.
Characterization and Assessment of Effects of Drying Temperature on Edible Mushrooms with HS-GC–MS
September 6th 2024To gain insight into the effect of drying temperature on its composition, headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC–MS) was used for the identification of volatile organic compounds (VOCs) of 86 mushroom samples that were divided into five groups and dried at different temperatures.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Real-Time Measurement of EPA Regulated HON Compounds and Environmental Pollutants Using SIFT-MS
September 6th 2024This application note describes the determination of method detection limits (MDLs) for the newly regulated HON (Hazardous Organic NESHAP) compounds, which validate SIFT-MS as an effective solution for measuring these toxic VOCs and other environmental pollutants in ambient air, whether at the fence line or in a mobile setting.
