Dwight Stoll has been awarded the EAS Young Investigator Award at the recent Eastern Analytical Symposium held in Plainsboro, New Jersey on 15th November. Professor at Gustavus Adolphus College, Minnesota, USA, Stoll completed his undergraduate degrees at Minnesota State University, Mankato, receiving B.S. degrees in plant biology and biochemistry in 1999 and 2001.
Taking a role in industry at Zir-Chrom Separations following his first graduation in 1999, Stoll gained an interest in separation science in the role and enrolled on the graduate programme in chemistry at the University of Minnesota. There he studied with Peter Carr and working on the development of fast, comprehensive two-dimensional liquid chromatography, using the principles of high temperature and ultra-fast gradient elution liquid chromatography to improve the overall speed of two-dimensional separations. Shortly thereafter he received his Ph.D. in analytical chemistry in 2007.
In 2008, Stoll accepted a faculty position as assistant professor in the Chemistry Department at Gustavus Adolphus College and in 2014 he was promoted to associate professor.
His active research projects include the development of rapid multidimensional liquid chromatography for both targeted and untargeted analysis in samples of moderate to high complexity. Active research projects in his laboratory touch upon most aspects of multidimensional separation methods, including optimization of isocratic and gradient elution HPLC, characterization of selectivity in reversed-phase HPLC, instrument development, and applications in biopharmaceutical analysis.
Stoll is the author or co-author of 49 peer-reviewed publications and two book chapters in the area of separation science, and is a named co-inventor on four patents.
Stoll has also recently taken over the authorship of LCGC’s flagship column “LC Troubleshooting” from long-time author John Dolan. To read his articles please visit: http://www.chromatographyonline.com/lc-troubleshooting-326
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 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.
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.
