Linda McGown Receives EAS Award for Outstanding Achievements in the Fields of Analytical Chemistry
The EAS Award for Outstanding Achievements in the Fields of Analytical Chemistry was presented to Linda B. McGown at EAS on 14 November.
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.
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.
Liquid Chromatography to Analyze Vitamin D Proteins in Psoriasis Patients
January 21st 2025Can a protein involved in delivering Vitamin D to target tissues have an altered serum profile in psoriasis patients with cardiovascular disease? Researchers used liquid chromatography (LC) to help find out.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
A Guide To Finding the Ideal Syringe and Needle
January 20th 2025Hamilton has produced a series of reference guides to assist science professionals in finding the best-suited products and configurations for their applications. The Syringe and Needle Reference Guide provides detailed information on Hamilton Company’s full portfolio of syringes and needles. Everything from cleaning and preventative maintenance to individual part numbers are available for review. It also includes selection charts to help you choose between syringe terminations like cemented needles and luer tips.
