We specialize on the investigation of small organic molecules from complex matrices. Hence, we are always looking for interesting mixtures to characterize.

To accomplish this goal, we develop fundamental research on sample preparation methods and analytical instrumentation. These solutions are used to solve complex investigations in multidisciplinary studies.

Available content:

  • Untargeted and targeted petroleomics using GC-HRAM-MS (link)

  • Classification of alcoholic beverages by FM-GCxGC and chemometrics (link)

  • The role of volatiles in the diagnosis of diseases in plants (link)


1. Sample preparation: static headspace sampling (HS), purge and trap sampling (P&T), thermal dessorption (TD), vacuum assisted sorbent sampling (see VASE), and solid-phase microextraction (SPME).
