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

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.

Two Guided Discussions will be held this year with the entire conference attendance (no break out groups). We invite you to attend and participate in these guided discussions during the workshop.
Removing the barriers from adoption of comprehensive two-dimensional chromatography
Caitlin N. Cain, Timothy J. Trinklein, Sonia Schöneich, Grant S. Ochoa, and Lina Mikaliunaite
Department of Chemistry, University of Washington, Seattle, WA, USA
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.
GCxGC, will it ever be in common use in the petroleum laboratories?
Lenny Kouwenhoven, Jop Bezuijen
Petroleum Analyzer Company
Christina Kelly
LECO Corporation
Jon Sims
Exxon
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
Three focus groups were held in 2022 with audience choice of which focus group to attend in breakout groups.
Topic 1: Simultaneous Detection
Organizers: Giorgia Purcaro and Flavio Franchina
Technical Moderator: Katelynn Perrault
Who is doing it? What are the combinations being used? What are the benefits? What are the
drawbacks? What is the difference in how they are used most commonly for multi-dimensional
GC vs. multi-dimensional LC?
Topic 2: Optimization
Organizers: Peter Tranchida, Bob Pirok, Magriet Muller
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
applications? Do newcomers need to know how to do robust optimization to get started?
Topic 3: External Software and Freeware Options
Organizers: Miriam Carolina Pérez Cova and Timothy Trinklein
Technical Moderator: Pierre-Hugues Stefanuto
Who is using freeware written using languages such as R or Python? What part of data
processing can be done in these programs? What are the pros and cons of using freeware
(validation, standardization etc.)? What are the benefits and drawbacks of external software vs.
embedded approaches being developed?
