A laser aerosol time-of-flight mass spectrometry (ATOFMS) that can be used for real-time measurement of the size and composition of individual aerosol particles has been designed and manufactured in our laboratory. Particles are introduced into the instrument through a particle beam interface, sized by measuring the delay time between two scattering lasers, and compositionally analyzed using a laser...
Laser mass spectrometry is a new chemical trace analysis method with high selectivity, sensitivity and speed. The mass-resolved resonance-enhanced multiphoton ionization (REMPI) spectra of chloroethylenes-trichloroethylene and tetrachloroethylene are firstly reported in the range 305.0-325.0 nm. The mass-resolved excited spectra and laser power index of fragment ions CCl+ are presented. The experimental...
