17th Multidimensional Chromatography Workshop Guidebook

Importance of the Topic

Multi-dimensional chromatography, including comprehensive two-dimensional gas chromatography (GC×GC) and two-dimensional liquid chromatography (2D-LC), has become a cornerstone technique for resolving complex chemical mixtures. Its high resolving power, enhanced sensitivity, and ability to generate rich chemical information make it indispensable across fields such as environmental monitoring, pharmaceuticals, food and beverage analysis, and forensic science.

Objectives and Workshop Overview

The 16th Multidimensional Chromatography Workshop, held at William & Mary’s Integrated Science Center in January 2026, aimed to bring together scientists, instrument developers, and end-users to share recent advances. The program featured keynote lectures, oral presentations, poster sessions, guided discussions, and networking events designed to foster collaboration and showcase emerging applications in GC×GC and 2D-LC.

Methodology and Instrumentation

The workshop covered a variety of advanced separation techniques:

• Flow-modulated and thermal-modulated GC×GC coupled with time-of-flight, high-resolution, quadrupole, and chemical ionization mass spectrometry.
• Comprehensive capillary and trap-based enrichment approaches for GC–olfactometry.
• Parallel use of electron and chemical ionization for detailed structural characterization.
• Hardware and software innovations in 2D-LC, including capillary-channeled polymer columns and machine learning–driven method development.

Key Themes and Discussions

Presentations highlighted applications of multidimensional separations to:

• Environmental analysis of PFAS, volatile organic compounds (VOCs), and plastic pyrolysis oils.
• Pharmaceutical development for small molecules, biologics, and therapeutic biomolecules.
• Food and beverage profiling, including aroma compounds in meads and fermented beverages.
• Forensic investigations, such as gunshot residue and post-mortem odor analysis.

Benefits and Practical Applications

Workshop contributions demonstrated how multidimensional chromatography delivers:

• Superior peak capacity for complex matrices.
• Enhanced compound identification via multidimensional data deconvolution.
• Improved quantitation and trace-level detection.
• Flexibility to tailor methods for specific industrial or research requirements.

Future Trends and Opportunities

Emerging directions include:

• Integration of machine learning and tensor decomposition for automated data processing.
• Miniaturized and on-chip extraction and separation systems for point-of-need analysis.
• Green chromatography approaches, such as hydrogen carrier gases and solvent-free extraction.
• Expansion of multidimensional methods to high-throughput and real-time applications.

Conclusion

The 16th Multidimensional Chromatography Workshop underscored the critical role of advanced separation techniques in addressing analytical challenges.
