Gas chromatography-Olfactometry (GC-O)

The system consists of a GC-FID connected in parallel to an Olfactory Detection Port (PHASER from GL Sciences; GC-O/FID) that allows for odour analysis and detection/identification, using human olfaction, of “smelly” compounds that are separated through GC and the classification of their odour contribution (description of what they smell like).

It can be applied to odour assessment, to solve odour/flavor problems and to detect and identification of key odorant-active compounds in complex mixtures, environment, food and biological matrices and consumer products.

Gas chromatography-ElectroAntennographic Detection (GC-EAD)

The system consists of a GC-FID connected with electroantennography (EAG).

The technique permits a “live” insect antenna to be used as an “ElectroAntennographic Detection” (GC-EAD), providing information on the compounds, separated though GC, that stimulate the olfactory sensilla of an insect, leading to the fast detection of bioactive compounds (specific chemicals an insect can smell) in complex biological matrices.

It can be applied to Chemical ecology, in semiochemicals research (e.g. pheromones discovery) and pest control/management.
