with a seminar entitled:
Multidimensional Separations in GC: Algae-Derived Bio-fuels, Advanced Olfactometry, Hybrid GCGC-MDGC Studies, and prep-GC with NMR

Abstract: In 2012, we introduced a number of novel approaches to speciation of volatile compounds. Many of these incorporate aspects of both comprehensive two-dimensional gas chromatography (GCGC) and multidimensional GC (MDGC). Often we profile the total composition of a sample using GCGC, then study specific analytes or target regions using MDGC. This presentation will report four case studies of the above research.
1. Measurement of thermally-stressed oxygenated degradation products in algal-derived jet fuel. Oxygenated products can form gums and block jet engine nozzles. They must be measured at low level (< 0.1%), but fuel matrix confounds the analysis. We use GCGC-FID and MDGC-MS to resolve this problem.
2. Precise olfactometry assessment for overall perception of aroma compounds in wine samples. Olfactometry requires good aroma resolution. We developed a system allowing 1D GC-O, 1D GC-FID, GCGC-FID, and MDGC-qMS/O in a single instrument.
3. Hybrid GCGC-MDGC methodology. This powerful approach can perform on-line extraction of single compounds or compounds classes during GC separation to provide ultrahigh resolution.
4. Prep MDGC. High resolution GC separation with single compound isolation, and NMR and X-ray crystallography structure determination.
