1What applications is Swisens Poleno useful for?
Swisens Poleno is used for longtime monitoring of particles in the air, like for example pollen or spores. It is the Swiss Army knife for aerosol research and helps to explore new particles but also to control particle formation for manufacturing processes.
2Which aerosol particle sizes does the Swisens Poleno measure?
Swisens Poleno measures PM1, PM2.5, PM10 and all particles up to 300µm in diameter.
3What information on aerosol particles do I get from Swisens Poleno?
Swisens Poleno provides the richest set of characteristics of every single particle on the market. Holographic images allow you to analyze volume, size and shape of every single particle. The fluorescence measurement setup provides further information about autofluorescence properties of each particle (fluorescence-intensity and -lifetime). Information about speed of particle and light polarization ratio complete the characteristic profile.
4How do you classify/identify the particles?
State-of-the-art machine learning algorithms process the rich set of characteristics from every single particle. The algorithms are able to differentiate between different particle classes / pollen types due to morphology and fluorescence properties.
5How can I see what the system is actually measuring?
Every Swisens Poleno device comes with software and a database with REST API interface. The local database can be accessed via webbrower based user interfaces like the Swisens Data Explorer and provide information about the status and actual measurements.
6How do you train the system to identify a new particle type?
To train the device for a new particle type, a sample of this specific particle type is needed. This sample is then nebulized with our Swisens Atomizer into the air and measured by a Swisens Poleno device. Cleaning of the aquired dataset is then done by post-processing the data by classical image processing and clustering algorithms. An additional visual check of the holograpic images can be done it necessary.
7What do I need to operate a Swisens Poleno?
For field operation, we recommend our complete Swisens Poleno monitoring station with an insulated weather protection housing. On site, there should be access to standard power mains. For roof installations, we recommend ground connection for lightning discharge and four rigging points. The whole monitoring station (incl. the device) weighs 130kg. The single device weighs 26kg.
8Can I operate multiple Swisens Polenos?
Swisens provides a simple solution for a central database, where local databases from deployed devcies can by synchronized to. This central database provides exactly the same interface like the local databases and is accessible via the same webbased user interfaces.
