Tesscorn provides advanced instruments for atmospheric aerosol measurement, including aerosol chemical composition analysis and aerosol mass spectrometry. These systems enable researchers to better understand the physical and chemical properties of aerosols and their impact on human health, air quality, and global climate, supporting the development of effective control strategies. Our portfolio includes a wide range of mass spectrometry-based instruments for real-time aerosol size and chemistry, as well as optical particle instruments for aerosol extinction and single scattering albedo measurements. We offer both research-grade and compact monitoring solutions, including near real-time metals measurement for ambient air, stack emissions, ambient carbon monitoring, and advanced bioaerosol measurement systems.
