Sensory Analysis of Odor

Electronic nose, instrument for sensory analysis of odor.

Instrumental odor assessment services

Odor is a key characteristic in sensory evaluation. The sense of smell perceives odor-related volatile organic compounds. Odor analysis is all the more important as, according to many scientific works, 80% of the perception of taste is actually a perception of odors by retro-olfaction.

Our electronic nose instruments can perform an overall odor evaluation as the human nose does, and some of these analyzers can additionally identify and characterize odor-related compounds.
Using this high-end technology, we can provide our customers bespoke contract analysis services to help them solve their odor issues.
