Using GC×GC–TOF MS to compare VOC profiles of food and beverages

Originally presented at the 19th International GC×GC Symposium in 2022

The poster entitled “Battle of the brands: Using GC×GC–TOF MS to compare VOC profiles of food and beverages” was presented by SepSolve Analytical at the 19th International GC×GC Symposium, which was held on 29 May–2 June 2022 as a virtual event.  

High-capacity sorptive extraction and trap-based focusing enhance sensitivity Imitation food and beverage products mimic the taste of popular branded products. However, flavour profiles are complex and consist of a broad range of chemical classes. It is important to be able to identify these volatiles during product development and in quality and authenticity studies.

Traditional sample preparation methods, such as headspace and SPME, are widely used, but often limited in terms of sensitivity.  

This poster demonstrates the use of high-capacity sorptive extraction with novel trap-based focusing to provide enhanced sensitivity and improved chromatographic performance. This improved performance, coupled with enhanced separation by GC×GC and highly-sensitive detection by time-of-flight mass spectrometry (TOF MS), gains greater insight into sample composition.
