Session 1060
Room 207C
This Tuesday morning session will be presided over by Matthew Klee of Agilent Technologies (Wilmington, Delaware), who also arranged the session. Capillary gas chromatography (GC) continues to be a workhorse separations technique in the analytical laboratory.
The session will open with introductory remarks from Klee. The first presentation in the session, “Characterization of Ionic Liquids for Chemical Analysis,” will be given by Daniel Armstrong of the University of Texas (Arlington). Armstrong, known for his work with chiral stationary phases, will discuss ionic liquids, which have received increasing attention in fields such as organic chemistry, electrochemistry, catalysis, physical chemistry, and engineering.
Next, John V. Seeley of Oakland University (Rochester, Michigan) will present a talk titled “Rational Stationary Phase Selection for Effective GCxGC Group-Type Separations.” Multidimensional GC separation techniques have been employed more widely, especially with the commercialization of the technology.
The next presentation, to be given by Aviv Amirav of Tel Aviv University, is titled “Pushing the Performance Envelope of Gas Chromatography — From Sample Collection to Data Analysis.” Amirav’s research interests include novel analytical instrumentation for detecting and analyzing pollutants in the environment as well as pharmaceuticals and drugs in biological fluids.
Milton L. Lee of Brigham Young University (Provo, Utah) will then present “Gas Chromatographic Sampling Technologies for Speed and Portability.” Lee’s areas of study have ranged from analytical, bioanalytical, and environmental research to techniques such as capillary chromatography, electrophoresis, mass spectrometry, and microfluidics.
The final presentation in the session will be given by Jim Luong of The Dow Chemical Company (Midland, Michigan) and is titled “Two-Dimensional Gas Chromatography and Capillary Flow Technology — Practical Industrial Applications.” Luong will further demonstrate the benefits of multidimensional separation.
New Study Uses MSPE with GC–MS to Analyze PFCAs in Water
January 20th 2025Scientists from the China University of Sciences combined magnetic solid-phase extraction (MSPE) with gas chromatography–mass spectrometry (GC–MS) to analyze perfluoro carboxylic acids (PFCAs) in different water environments.
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 ion 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.
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.
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.
Oasis or Sand Dune? Isolation of Psychedelic Compounds
January 20th 2025Magic mushrooms, once taboo, have recently experienced a renaissance. This new awakening is partially due to new findings that indicate the effects of psilocybin, and its dephosphorylated cousin psilocin may produce long lasting results for patients who might be struggling with anxiety, depression, alcohol and drug abuse, and post-traumatic stress disorder. Hamilton Company has developed a methodology for the isolation and identification of 5 common psychedelic compounds used in the potential treatment of disease. The PRP-1 HPLC column resin remains stable in the harsh alkaline conditions ideal for better separations.
