7 April 1995 Real-time chemical analysis of aerosol particles
Author Affiliations +
An application of an ion trap mass spectrometer (ITMS) for real time chemical analysis of airborne microparticles is described. Fragmentation analysis of organic chemicals condensed on a microparticle's surface has been demonstrated using laser induced desorption ionization and MS/MS techniques with ITMS. An on-line atmospheric particle sampling system has been designed and interfaced to the ITMS. A dual particle detector system using optical fibers has been designed and timing electronics have been developed for the particle speed measurements required in order for the desorption laser to intercept the particles.
