Analysis of the Provenance of Whiskies Through SPME-GCxGC-TOFMS
Move beyond “more peaks”
Discover how two-dimensional chromatography transforms complex chemical data into clear sensory insights.
Whisky is a chemical labyrinth of thousands of volatile compounds. In many cases, the most influential flavor markers exist at trace levels or are hidden by “coelution” in standard 1D GC-MS. If you can’t see the compound, you can’t control the quality.
In this technical deep dive, Dr. Damien Steyer (Founder & CEO of Twistaroma) reveals how to unmask the hidden chemical fingerprints of global spirits using the LECO Pegasus BTX 4D with ChromaTOF Sync 2D.
What Will You Learn?
- Superior Separation: How GCxGC uses two columns to resolve thousands of peaks that 1D GC simply misses.
- The Power of TOFMS: Utilizing high-speed, full-spectrum detection to capture data with ultimate sensitivity.
- Hydrogen as a Carrier Gas: Learn how to achieve excellent chromatographic performance while reducing costs and reliance on helium.
- Getting Data from Drama: How to use PCA, ANOVA, and Heat Maps to link specific markers (like phenols, pyrazines, and lactones) to recognizable sensory traits like smoke, fruit, and roast.
Presenter
Dr. Damien Steyer is founder and CEO of Twistaroma, a laboratory specialist dedicated to the analysis of volatile and odor-active compounds. With more than 15 years of experience in aroma science, gas chromatography, and solvent-free extraction techniques such as SPME, his work focuses on the detailed characterization of complex matrices including spirits, essential oils, and plant-derived products.
Drawing on a strong background in analytical chemistry and flavor research, Damien helps translate advanced chemical data into meaningful insight for product development, quality evaluation, and sensory understanding
