On October 30, 2013, The Chromatographic Society (ChromSoc) and the North West Region of the Analytical Division of the Royal Society of Chemistry (RSC) will be holding another of their successful Advances in GC meetings in Runcorn, Cheshire, UK.
Our own Jaap de Zeeuw has been invited to speak, joining experts from throughout academia and the chromatography industry.
Column Selection: There is More to Life Than a Boiling Point Column?
Jaap de Zeeuw (presenter)
Abstract: Column selection remains an interesting challenge. On one side, we like to keep things as simple as possible, using only nonpolar polydimethyl siloxane–based phases (typically referred as “boiling point” columns) that have proven to be robust. With such phases coated in long capillaries, we have the efficiency to do the separation for us. And if efficiency does not do the job, the column can also be used with a mass spectrometer, and again, a separation is obtained.
The other side is to use selectivity to maximize separation. Here we can use relative short columns to do the separation. The main advantage is in analysis time and cost per analysis. Selectivity is provided by stationary phase interactions, and we have seen that for a number of applications, “selectivity” allows us to do unique separations using not only GC-FID, but also for applications where even the mass spectrometer does not qualify.
Today’s stationary phase chemistries allow us to modify phases while maintaining robustness. Practical operation and temperature range is comparable with the “boiling point” columns.
According to the organizers, “GC is still the technique of choice for analyzing both volatile and semivolatile compounds, but as we move to more difficult matrices, more is being asked of the technique in terms of separation and limits of detection. The meeting sets out to give an overview of current GC technologies and methodologies, information on newer detection/separation solutions, and case studies from all the main user areas.” Especially given our own focus on cutting-edge technology for lowering detection limits and increasing selectivity, Restek is excited to be an active participant in this year’s event. In addition to the full meeting program, there will be an instrument exhibition—and Restek Thames UK will be present to discuss our latest innovative chromatography solutions with attendees.
