This Monday afternoon oral session, Environmental: Innovative Approaches and Instrumentation, will be held 2:30–4:30 pm in room 113 ABC. Nelson Vinueza of North Carolina State University will chair and preside the session. Six talks will take place during this session.
Sarah Choyke of the Colorado School of Mines, in Golden Colorado, will be the first presenter, with a talk titled “Enhanced PFAS Precursor Detection in Fractionated AFFFs with Orbitrap Mass Spectrometry.” Following this presentation, Virginia Benefield of MTSU, in Murfreesboro, Tennessee, will speak on “Toxicant Analysis of the Particulate Matter in Biomass Smoke Using GC/MS and DART–MS Methods.”
Next, Jeffrey Gilbert of Corteva Agriscience, in Indianapolis, Indiana, will discuss “Structural Elucidation of Environmental Metabolites Using Stable Isotope Labeling Combined with EAD, CID, UVPD Fragmentation and Ion Mobility Mass Spectrometry.”
Ashley Perkins of the University of South Carolina, in Columbia, South Carolina will present a talk titled “Emerging Unregulated Disinfection By-Products: Can Brita Filters Remove Them?”
The next presentation will be from Jessie Matarrita Rodriguez, who will give a talk on “Combining Ion Chromatography and Liquid Chromatography Coupled to High-Resolution Mass Spectrometry for Suspect Screening of Pesticides and Transformation Products.”
And finally, a Roundtable Discussion for Environmental: Innovative Approaches and Instrumentation will close the session. Jennifer Watson of the ASMS Office in Sante Fe, New Mexico will preside.
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.
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.
