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 – 10 μm with the integration time of 1 s. To obtain additional information about the PSD of larger particles (0.5–10 μm) 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 of thermal 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 process was 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-MS signal with a concentration of particles >300 nm was observed.
