New Wave of Gas Chromatography

Session 340, Room S404bc, 8:30 a.m.

This Monday morning session will be presided over by Milton L. Lee of Brigham Young University, who also arranged the session.

The session will open with introductory remarks from Lee, followed by his presentation, “Changing Faces of Gas Chromatography.” He will discuss the evolution of the technique and its instrumentation to “smart” GC instruments and methods.

Next, Stanley D. Stearns of Valco Instruments will present a talk titled “Resistively Heated Gas Chromatography.” His presentation will describe direct resistive heating using a nickel wire or nickel plating on the column with a temperature controller that employs sophisticated control algorithms.

The third presentation in the symposium will be given by Robert E. Synovec of the University of Washington and is titled “Advances in Instrumentation and Data Analysis Methods to Improve Peak Capacity in GC–TOFMS and GCxGC–TOFMS.” His talk will look at some recent advances in instrumentation development for the two techniques.

After a brief recess, Edward T. Zellers of the University of Michigan will present “A Microfabricated Comprehensive Two-Dimensional Gas Chromatograph (µGC X µGC).” Zellers will discuss the development and preliminary characterization of a microfabricated comprehensive 2D GC system that includes silicon micromachined components.

The final presentation in the session, titled “Properties of Thermal Gradient GC Separations,” will be given by H. Dennis Tolley of Brigham Young University. His presentation will address topics such as virtual column length, correction of imperfect separation, restriction of peak broadening over time, application to 2D separations, and on-column concentration of analytes.
