Guided Discussion Groups 2024

Advantages and Limitations of GC×GC in Government and Industrial Laboratories

• Haleigh Boswell (Chevron Technology Center)
• Sarah Prebihalo (U.S. Food and Drug Administration)

​Comprehensive gas chromatography (GC×GC) is a common technique used in government and industrial laboratories; however, it has struggled to gain widespread acceptance due to perceived complexity and a lack of standardized and validated methods. Furthermore, the technique is not directly comparable to historical data sets and previously used analytical techniques. Overcoming these challenges and limitations in non-academic laboratories is a critical aspect of research by experts and advanced GC×GC users. Advanced users must be vocal advocates, highlighting the advantages of GC×GC in cases where the additional separation data can be advantageous. By addressing the benefits and limitations of this technique, this discussion will aim to address how we may elevate GC×GC in industrial and government laboratories, including, but not limited to, the role of obtaining employment in these sectors, allowing for further integration into the GC×GC community.

Preliminary Results in the Development of a System Performance Standard Reference Test Mixture for Comprehensive Two-Dimensional Gas Chromatography

• Jean-Marie D. Dimandja (FDA/ORA)
• Pierre-Hugues Stefanuto (University of Liege)

GC×GC system performance is influenced by many parameters, including modulator type, column set, detection method, and data processing software. This discussion will be focused on the development of a standard test mixture that can be used to compare GC×GC system performance across instruments and laboratories.
