Monday's "General Interest: LC/GC" session delved into a wide array of new techniques and discoveries in the scientific and academic LC/GC communities.

Monday’s "General Interest: LC/GC" session delved into a wide array of new techniques and discoveries in the scientific and academic LC/GC communities.

The session began with a talk from Robert Freeman from the Restek Corporation entitled, "Development of a New Series of Low-Bleed, High-Inertness Capillary GC Columns, Through Improved Deactivation Chemistry and Stationary Phase Synthesis." Following Freeman was Richard J. Lake, also of Restek Corporation. Lake's presentation, "Improving the Durability and Selectivity of Silica-Based Stationary Phases for Use in High pH Applications," offered insight into silica-based stationary phases.

Also presenting Monday morning was Leonard M. Sidisky from Supelco. His presentation, "Selectivity Comparison of Cyclodextrin Based Capillary GC Stationary Phases," focused on a study that compared and contrasted the unique selectivity provided by cyclodextrins that were derivatized with a variety of functional groups, such as trifluoroacetyl, permethyl, and dimethyl among others.

The final presentation before the recess was titled "Characterization of Phosphonium Ionic Liquids through a Linear Solvation Energy Relationship and Their Use as GLC Stationary Phases." The discussion, given by Zachary S. Breitbach from the University of Texas, Arlington, highlighted some key findings in a series of experiments that present eight new monocationic and three new di-cationic phosphonium based RTILs used as GLC stationary phases.

After the recess Leonard M. Sidisky took the stage again for a talk titled, "Investigation of the Selectivity of Ionic Liquid Stationary Phases for Capillary GC." Followed by that was another presentation from Richard J. Lake titled, "Using Stationary Phase Selectivity to Optimize UHPLC Analyses." Christopher Linton, from Valco Instruments, was up next with a discussion on "Novel Advances in Traditional Gas Chromatographic Stationary Phases." Rounding out the session was Maricar Tarun from Millipore Corporation with a presentation titled, "Influence of Eluent Quality on Gradient HPLC Separations."
