<h3><strong>Guided Discussion Groups 2024</strong></h3>
<h5><strong>Advantages and Limitations of GC×GC in Government and Industrial Laboratories</strong></h5>
<ul>
<li>Haleigh Boswell (Chevron Technology Center)</li>
<li>Sarah Prebihalo (U.S. Food and Drug Administration)</li>
</ul>
<p>​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.</p>
<h5><strong>Preliminary Results in the Development of a System Performance Standard Reference Test Mixture for Comprehensive Two-Dimensional Gas Chromatography</strong></h5>
<ul>
<li>Jean-Marie D. Dimandja (FDA/ORA)</li>
<li>Pierre-Hugues Stefanuto (University of Liege)</li>
</ul>
<p>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.</p>
