摘要：

A new instrument is presented allowing in situ single-particle analysis by pulsed laser-induced ionization and time-of-flight mass analysis. Particles are introduced into the mass spectrometer through a differentially pumped interface system, detected by light scattering caused by a He-Ne laser beam and ionized by a pulsed UV laser. Instrumental performance is demonstrated using artificial aerosols. Application to on-line mass analysis of ambient aerosol particles is reported for the first dine.
