Pollen/Biological Aerosol Automatic Monitor

System Introduction

Pollen and various biogenic particles in the air belong to the scope of bioaerosols, playing an irreplaceable role in the interactions between the Earth system, especially in the atmosphere, biosphere, climate, and public health. It is an important research topic in related fields such as public health, pollen load, air pollution, climate change, and their interdisciplinary fields.

SwisensPoleno JupiterPollen/Biological Aerosol Automatic MonitorThrough technologies such as digital holographic imaging, fluorescence spectroscopy, light scattering, and polarization measurement, a digital fingerprint containing morphological data and chemical composition can be generated for each particle entering the analyzer. Further processing and classification can be achieved through machine learning algorithms, enabling autonomous identification and automatic measurement of the concentrations of pollen, spores, bioaerosols, and solid particles in the air.
