Ambient Aerosol Research










Interest in particle research in the field of atmosphere and air quality has been continually increasing over the past decades when correlations between particle concentration, size and composition and adverse health effects have been found. Particles have also been found to have effect on climate and in spite of extensive research they still remain an uncertainty in climate change modeling. Since particle size, concentration and composition vary depending on the measurement location, detailed analysis of the particles is needed to determine the source and characteristics of the particles in the air.

Common requirements for the instrument include:

  • Capability to measure both low and high concentrations to allow the use of the same instrument for measurements in urban, rural and remote areas
  • Ability to detect changes in real-time to determine also short-time scale changes in the sample
  • Ability to measure concentrations of different sized particles simultaneously
  • Ability to allow analysis of chemical composition of different sized particles to determine particle source and/or detailed characteristics of particles to determine e.g. toxicity of the particles in the air.
