M²AS | Mass & Mobility Aerosol Spectrometer
Mass & Mobility Aerosol Spectrometer (M²AS)
The M²AS combines several established aerosol instruments; the Unipolar Diffusion Aerosol Charger (UDAC), Centrifugal Particle Mass Analyzer (CPMA) and Condensation Particle Counter (CPC) with a novel Mobility Separator.
Unique Measurements
In a single scan of the input aerosol, the M²AS measures particle mass, mobility, charge state and concentration.
Aerosol Characterisation
