Aerosol Mass Spectrometer

Description

The 3800 series ATOFMS instruments provide single particle size range from 30 to 3000 nanometers. They use an aerodynamic sizing technique that provides results similar to those obtained from a TSI Aerodynamic Particle Sizer spectrometer. The aerodynamic size data serves as a timing trigger and calculates when each particle will be in the focal zone of an ablation laser. This laser desorbs and ionizes the particle for chemical analysis in a bipolar, time-of-flight mass spectrometer. Bipolar ion detection-where positive and negative mass spectra are obtained for each particle using separate ion detectors- giving you additional information about the particle and its source. Windows based software controls instrument functions and data acquisition.
