Past Guided Discussion Groups
2025 - Transition to green chemistry, challenges and opportunities for analytical revolution
Melissa Dunkle
Dow Benelux
Pierre Giusti
TOTAL Energies
Jef Focant
Université de Liège
Over the last five years, the political actions to minimize climate change have deeply modified the landscape of chemical and energy industries. These ambitious targets are currently driving the research and development effort to greener solutions for material, chemical, and energy production.
During this discussion group, we will discuss with key actors of the field to see the challenges and opportunities for analytical technology in this green revolution.
2025 - Teaching GC×GC to students, post-docs, and staff
Chris Freye
Colleen Ray
Michelle Corbally
Los Alamos National Laboratory
Teaching GC×GC to people in different stages of their careers, especially with diverse analytical chemistry backgrounds, often requires a different approach. Those who learn GC×GC as part of their graduate school experience have multiple years to master the technique whereas people who are trained on the job (post-docs and staff) have significantly less time to attain the same level of proficiency. This discussion will focus on instructional approaches and difficulties in training people with various backgrounds on GC×GC. Special attention will be given to common difficulties encountered regardless of career level.
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.

2023 - Removing the barriers from adoption of comprehensive two-dimensional chromatography

Soraya Chapel
KU Leuven, Leuven, Belgium
Comprehensive two-dimensional gas (GC×GC) and liquid (LC×LC) chromatography are well-established separation techniques that exhibit enhanced resolving power over their one-dimensional counterparts. With improvements in commercial instrumentation and data analysis platforms, performing a GC×GC or LC×LC separation and analyzing its output are easier now than ever before. However, despite these developments, the broader analytical community often perceives comprehensive two-dimensional chromatography as complex, difficult, and intimidating. How do we address this stereotype and make these separation techniques approachable to the broader community? Following each step in the established analytical workflow, this discussion group will identify common misconceptions about instrumentation, method development/optimization, and data analysis. By addressing these concerns, this discussion will aim to instill confidence in analysts and provide them tools for applying these separation methods to various application areas.
2024 - GCxGC, will it ever be in common use in the petroleum laboratories?
Jop Bezuijen
Petroleum Analyzer Company
Christina Kelly
LECO Corporation
Jon Sims
Exxon
Petr Vozka
California State University, Los Angeles
Legislation, commercial contracts or process control require standardized methods or procedures to ensure product results from all parties involved can be compared to meet contract requirements and resolve disputes.
Standardized method development and adoption is a collaborative process which requires buy-in from many competing interests before new methods are accepted. Innovative or unfamiliar technologies need to overcome market resistance to change, bureaucratic inertia within standardization committees, and the tendency of legacy market suppliers to protect their economic interest. All of these pre-existing stakeholders need to be brought into agreement to allow the new technology into the market space. With these difficulties as background, Lenny Kouwenhoven will talk about her real world experience in bringing the first GCxGC test method for the petroleum market through the ASTM method development process. In addition, the first preliminary ILS data for the GCxGC method will be presented and discussed. The path forward for European and Asian adoption will be overviewed and contrasted with ASTM procedures.

2022 - Topic 2: Optimization

Technical Moderator: Dwight Stoll
How do you optimize your separation? What issues are related to the use of mass spectrometry? Is there a need for optimization software tools? What do you consider in an optimal 2D separation? Are users moving towards a standard 2D column set for various
