The importance of accurate analysis methods for EtO and 2-CE in food is essential and the demand for robust methods that are able to deliver high sample throughput with minimal instrumental downtime is high.

This article looks at the benefits of combining dynamic headspace sampling (DHS) with capillary GC–TOF-MS as a tool for untargeted analysis of aroma compounds in food and beverages. Applications for the analysis of strawberry yoghurt, chocolate, and red wine are described.

When possible, GC analysis is performed under retention time locked conditions, meaning that allergen elucidation and quantification is based on mass spectral data (scan mode or specific ion detection mode) and on retention time.
