| Definition | The TSI 3800 Aerosol Time-of-Flight Mass Spectrometer (ATOFMS) provides size and chemical characterisation of aerosol particles in the size range 0.1-3.0 um. Air is pumped through the system in real time and particles are counted and timed as they pass each of two lasers in the sizing chamber. The particle size is determined from the particle's velocity through the sizing chamber. The particle is subjected to ultraviolet desorption and ionisation in the mass spectrometer chamber. Positive and negative ions are identified by separate detectors, based on their time of flight through the mass spectrometer chamber. | ||
