Olfactometer

ONOSE-8® is a stationary dynamic dilution olfactometer. Designed for laboratories and research centers desiring to perform odour analyses, this state-of-the-art olfactometer is used for quantification of odours with the use of up to 16 panelists. The olfactometer operating system, Olfaware, is easy to use and powerful. Onose-8 can perform a wide variety of tasks linked to olfactometric analyses, quickly and precisely. The olfactometer and the operating system can be modified to adapt to the client’s needs.

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.

Operation of olfactometer ONOSE-8®

Olfaware software

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.

    Components for the olfactometer ONOSE-8®

    The Onose-8® olfactometer is composed of accurate mass flow controllers with a reading error of <0,2% FS (0% to 20% of the mass flow scale) and <1% reading (20% to 100% of the mass flow scale). All the components of the olfactometer that are in contact with fresh air or odours are made exclusively of Teflon, stainless steel or glass. These components allow a fast purge and a minimum risk of contamination during olfactometric analyses.

    The components of Onose-8® offer, but not limited to, the following characteristics:

    • Fully automatic dilution system
    • Two levels of dilution, from 24 to 217 standard and from 24 to 221 optional
    • Easy modification of the dilution step factor
    • Simultaneous analyses by up to 16 panelists
    • Touch screen pads used by panelists as a voting platform
    • Operating station equipped with a 24” wide touch screen
