What is it?
Each odour has a unique ‘fingerprint’ related to its chemical composition, allowing the E-nose to compare and identify each odour detected, in the same way a human nose would first detect an odour and then process the stimuli and use memory to identify the odour type.
What can it be used for?
What can it NOT be used for?
E-noses can not measure the intensity and the pleasantness of the odour (hedonic tone). When used for the estimation of odour concentration at emissions, electronic noses shall be trained with samples that are analysed by dynamic olfactometry. For this reason, they cannot substitute dynamic olfactometry.
