Aerosol Measurement Technology, FHNW School of Engineering and Environment

Aerosol particle measurement is used for environmental immission monitoring and for the measurement and characterization of particulate emissions from combustion processes, such as diesel engines or biomass combustion.

The Institute for Sensors and Electronics is also familiar with standard techniques in the aerosol field. In addition to classical measurement techniques (SMPS, CPC, etc.), our competencies include the development of new instruments based on light scattering, light absorption (e.g., via photoacoustics), and carbon analytics. Another core competency is the development of reactors to simulate atmospheric transformation processes.

In the context of research, highly precise and highly sensitive current measurement systems have been developed, with the capability to measure in the sub-femtoampere range. Further work includes aerosol generation and filtration. For this purpose, the Institute for Sensors and Electronics operates a well-equipped Aerosol Technology Laboratory.
