John Dolan’s recommendation for Session 1120, “HILIC- Fundamentals and New Applications,” was presided over by Olujide T. Akinbo of Butler University. The session focused on innovations and breakthroughs in HILIC.
The first presentation, from Yury Zelechonok of Sielc, titled “HILIC, Mixed-Mode and AQ- Three Approaches for Analysis of Polar Compounds. Their Scope, Limitations, Applications,” was focused on the analysis of polar compounds. Following this presentation was one from David S. Bell of Sigma-Aldrich entitled, “New Insights into Retention and Selectivity in Aqueous-Normal Phase/HILIC Separations.”
Next on the agenda was “Fundamental Importance of Buffer Cation and Anion on the Robustness and Selectivity of HILIC Separations of Basic Compounds,” given by A. Carl Sanchez of Phenomenex. Last up before a the recess was a presentation by Joseph Pesek of San Jose State University on “Why Aqueous Normal Phase and HILIC are Different.”
Immediately following the brief recess was, “Undirected Metabolomic Analysis of Islets of Langerhans by Hydrophilic Interaction Liquid Chromatograph- Time of Flight Mass Spectrometry,” presented by Matthew Allen Lorenz of the University of Michigan. Finally, there was a presentation on “The HILIC Behavior of Reversed-Phase/ Ion Exchange Mixed-Mode HPLC Columns and Applications,” presented by Xiaodong Liu of Dionex Corporation.
The 26th Norwegian Symposium on Chromatography
March 29th 2024The 26th Norwegian Symposium on Chromatography was held 21–23 January 2024. The symposium has strong traditions in the Norwegian separation science community, serving as a forum for excellent scientific talks, networking, and social events.
Adjustable Polyacrylamide Stationary Phases Enhance Separation Performance in Liquid Chromatography
June 12th 2023Adjustable polyacrylamide stationary phases developed by researchers enhance separation performance in liquid chromatography, according to a recent publication. The study demonstrates the synthesis of vinyl modified silica and the successful preparation of polyacrylamide modified silica (PAM-SIL) stationary phases, allowing for fine control of separation performance.
An Interview with AI About Its Potential Role in Separation Science
May 17th 2023We interviewed an AI program (ChatGPT) for LCGC North America asking questions about AI and its role in various applications for separation science to include data analysis, and high performance liquid chromatography (HPLC), hydrophilic-interaction chromatography (HILIC), reversed-phase liquid chromatography (RPLC), liquid chromatography–mass spectrometry (LC–MS), gas chromatography–mass spectrometry (GC–MS), high resolution mass spectrometry (HRIM–MS), high resolution tandem mass spectrometry (HRMS/MS), and related topics.
