1. Introduction

The Aryballe NeOse™ is a portable "digital nose" designed for precise odor detection. Utilizing a 64-gas sensor array embedded in a bio-functionalized silicon photonic chip, it emulates human olfaction to detect and analyze diverse volatile molecules with high sensitivity. This handheld device connects to a web application for real-time dynamic sensograms and automatic odor classification, making it ideal for applications in food, cosmetics, and industries.

4. Basic Operations – Available modes

4.1. VOCs Mode (Intensity Monitoring) : Allow detecting an event related to a local concentration of VOCs

• Bring the NeOse as close as possible to the VOCs source to be analyzed

• Read the information displayed on the screen

4.2. Recording an Odor: Record the event for further analysis via the dedicated interface

• Activate the “RealTime Olfactive Sensing” mode and wait for 5 seconds to record the baseline.

• Press "start recording".

• Bring the NeOse as close as possible to the VOC source to be analyzed

• After observing the stabilization of the signal, stop recording, add a label, make sure to select the zone of interest in blue with your cursor and save the data. 

• A notification will appear when the process is complete.
   

4.2.1 Selection of the interested zone

• We recommend selecting the plateau phase: 

• Example of wrong selection:

4.2.2 Record visualization

• Click on “record” to see the test recording

4.3. Testing a sample Containing VOCs comparing with a database

• Activate a predefined model using the dedicated page.

• Make the selection of the records you would like to include in your model, then click on the button “Analyze 9 records”.

• Scrolling down, the PCA projecting all the selected records will be visible.

• Adapt the parameters of tolerance as necessary and save the model.

• Go to the “RealTime Olfactive Sensing” mode and switch on the Recognition version. The model will be visible on the right of the page.

• Bring the NeOSE close to the sample.

• Read the results displayed on the interface.

5. Troubleshooting

It is possible that the Bluetooth connection between the NeOse and the connected device is interrupted in this case return to 3.2
