The dynamics of aerosol particles formed during nanosecond laser ablation of glass and steel samples was studied in the Laser Ablation–Inductively Coupled PlasmaMass Spectrometry (LA-ICP-MS) system. In order to follow the evolution of particle size distribution with high time resolution during the laser ablation process, two fast response aerosol spectrometers were used. Engine Exhaust Particle Sizer (EEPS) together with Optical Particle Sizer (OPS) provided Particle Size Distribution(PSD) in the range 5.6 nm–10um with the integration time of 1 s. To obtain additional information about the PSD of larger particles (0.5–10um) in more detail, an Aerodynamic Particle Sizer (APS) recorded average PSD of each ablation (80 s). To investigate the effect of the sample matrix on aerosol dynamics and composition,glass NIST 610 and steel F4 samples were studied. Spot and line ablation mode was applied to compare the behavior of both ablation modes in time. The degree ofthermal effect and fractionation was studied from the structure and size of ablation craters, the structure of particles and the LA-ICP-MS signal. The ablation processwas influenced mostly by the material itself even if the ablation mode also plays an important role on the formation of aerosol. A significant correlation of ICP-MSsignal with a concentration of particles larger than 300 nm was observed.
