Olfactometer
The olfactometric analysis techniques that can be performed by ONOSE-8® are the following:
- Dilution to threshold in order to determine the odour concentration of a sample,
- Evaluation of the offensiveness of an odour by comparison with n-butanol,
- Evaluation of the hedonic tone according to different comparison scales,
- Evaluation of the panelists’ olfactory detection threshold with n-butanol.
The Olfaware software is the operating system and interface to operate the olfactometer. Developed specifically for Onose-8, the Olfaware software allows a total control over all steps of an olfactometry analysis.
Olfaware software offers the following characteristics:
- Allows data input regarding clients information, samples descriptions, panelists and analysis information, etc.
- Automatically produces a database including all relevant information regarding the analysis in progress
- Production of a blank sample, automatic purging protocol, automatic sampling bag air filling, etc.
- Real time verification of panelists’ results
Not only is the software polyvalent, but it can also be entirely modeled to fit the client’s specific needs. During an olfactometric analysis, the votes of the panelists are recorded through touch screen electronic tablets.
Intuitive and easy to use, these tablets are connected to the Olfaware operating system with a wireless network in order to present to the operator the panelists’ voting answers in real time.
The ONOSE-8® olfactometer is used to perform olfactometric analyses according to the following standards:
- ASTM 679
- EN 13725
- VDI 3881 & 3882
