A device developed by Aryballe Technologies (Grenoble – France) and based on Surface Plasmon Resonance (SPR) imaging was used to measure odorous compounds. One advantages of such a device is to propose a large number of receptors inside the measurement cell.
This aspect allows a distinction capability that cannot be obtained with classical instruments. Presented results show a strong capacity of distinction of compounds even isomers and a detection limit dependent on the family of compounds and the size of the molecule.
