Wednesday Morning Session on Surface Properties
A Wednesday morning session titled "Surface Properties, Interactions and Retention Selectivity" will be held in Ballroom B starting at 10:30 a.m. The Session Chairs will be Georges Guiochon of the University of Tennessee (Knoxville, Tennessee) and Wolfgang Lindner of the University of Vienna (Vienna, Austria).
A Wednesday morning session titled “Surface Properties, Interactions and Retention Selectivity” will be held in Ballroom B starting at 10:30 a.m. The Session Chairs will be Georges Guiochon of the University of Tennessee (Knoxville, Tennessee) and Wolfgang Lindner of the University of Vienna (Vienna, Austria).
The first presentation in the session will begin at 10:30 a.m. and will be given by Marja-Liisa Riekkola of the University of Helsinki (Helsinki, Finland). The title of the presentation is “Ingenious Electrochromatographic Approaches for Surface Interaction Studies.”
Next, a talk titled “Structural Variation of Solid Core and Thickness of Porous Shell of 1.7 µm Core-Shell Silica Particles on Chromatographic Performance” will be presented by Csaba Horváth Young Scientist Award Nominee Jesse O. Omamogho.
Omamogho’s discussion of the core-shell LC column particles will be followed by a presentation by Charles A. Lucy of the University of Alberta (Edmonton, Alberta, Canada) titled “Insights into Retention and Selectivity in Ion Chromatographic Separations of Inorganic Anions.”
The final presentation in this Wednesday morning session will be given by Uwe Dieter Neue of Waters Corporation (Milford, Massachusetts). Neue’s talk is titled “Selectivity in Reversed-Phase Separations.”
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.
