Paper Abstract

In this paper, Aerosol time-of-flight mass spectrometer optical particle size measurement system optimization and influencing factors are studied. Optimized the distance between nozzle and the skimmer, using a shorter wavelength light source measurement, Aerosol particle size measurement from the previous limit of 260 nm to 120 nm. Study found that the particles scattered light intensity is connected with light intensity and wavelength of the light source. particle size measurements using shorter laser wavelengths or greater energy, which can measure smaller size diameter within certain range. combining particle beam focusing aerodynamic lens system device, the particle size of air the time-resolved measurement of 256 / min, Measurement of time-resolved mass spectrometry to 170 / min, MS hit rate of 64.5%.
