Science from Beyond the Grave: a Virtual GC Symposium
Three GC/MS Experts embrace the 'spookier' side of mass spectrometry. |
Principles and Instrumentation of GC×GC and ToF-MS
Improved sensitivity and group-type selectivity makes GC×GC ideal for MOSH/MOAH separations - saturated species can be separated from the unsaturated or aromatic ones. Hans-Gerd Janssen, University of Wageningen, Netherlands. |
Understanding Food Off-Flavors and Malodors
Utilizing Gas Chromatography-Olfactometry (GC-O) can help identify active odor compounds in complex mixtures. But, what happens if GC-O does not identify a compound, but an off-flavor or malodor is still present? |
Application of Two-Dimensional Gas Chromatography with Mass Spectrometric Detection for Analysis of Pesticide Residues in Foodstuffs
The Czech Agriculture and Food Inspection Authority has been using GCxGC-TOFMS for the analysis of pesticide residues in food of plant origin since 2005. Radim Stepan will talk about the advances in the instruments and the analyses they have used for pesticide residue analysis in cooperation with the University of Chemistry and Technology Prague. |
Food Safety: A Journey Beyond the MOSH&MOAH Hump in Food Determination
The current analytical method for the quantitative determination of Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) is LC-GC-FID, but the chromaticagraphic profile obtained is too often just a hump of unresolved substances. However, GCxGC-TOFMS/FID is the most promising solution to characterize MOSH and MOAH in detail and to detect markers that can help identify and act on the source of contamination. Giorgia Purcaro [University of Liege] will introduce the challenges of MOSH/MOAH analysis and talk about what adding a GCxGC-TOFMS analysis to your process can do for your results. |
