Guided Discussion Groups

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.
