When measuring odours, 2 different methods can be used depending on the characteristics of the Odours (1).
- Physicochemical Methods: Gas Chromatography, FID, piezoelectric sensors (electronic noses), colorimetric tubes, etc.
-
Sensory methods: Olfactometry, Nasal Ranger, psychometric assessment, etc.
The physical-chemical methods are suitable when the Odorous compound is known or when we pretend to monitor the emissions of certain installations in continuum to control the presence of gas leakages associated with odorous compounds. This methods are not very specific or sensitive nowadays.
Although it is a relatively new technique, Olfactometry is presented as the future standard to measure odours until other devices, such as the electronic nose, are further developed.
