The High Resolution Aerosol Mass Spectrometer (HR-AMS) is an in situ airborne mass spectrometer designed to detect aerosol composition and chemistry. It is a modified version of the Aerodyne Aerosol Mass Spectrometer developed by the University of Colorado. It measures the mass concentrations of aerosol particles ranging from 50 nm to 1 μm. HR-AMS detects aerosol composition through impaction at 600 °C, followed by electron ionization and mass spectral analysis. It has a measurement sampling rate of 1 Hz.
