Description:The Aerodyne aerosol mass spectrometer (AMS) is used extensively to measure the chemicalcomposition of non-refractory submicron aerosol particles for laboratory and atmosphericfield studies. Typical AMS calibration methods are mass-based, involving generating pure or mixtures of particles with a known size and number concentration. Here we present a new calibration method using a heated platinum/molybdenum catalyst-based conversion tech- nique that provides an independent measurement of reactive nitrogen (N r) and total organic carbon (C y) traceable to gas-phase standards of nitric oxide (NO) and carbon dioxide
