| Description | Laser ablation was performed by nanosecond laser ablation systems at the wavelength of 193 and 213 nm. Different materials and different ablation conditions were used for the study of the aerosol formed during laser beam-sample interaction and for the study of the ablation craters. The particle size distribution (PSD) of dry aerosol was monitored simultaneously with LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) analysis using different aerosol spectrometers – Fast Mobility Particle Sizer (FMPS), Scanning Mobility Particle Sizer (SMPS) and Aerodynamic Particle Sizer (APS). The unique combination of LA-ICP-MS and FMPS offers the possibility of controlling the particle size distribution every 1 s of the ablation process in the size range of 5.6 – 560 nm. Ablation craters were additionally studied using scanning electron microscope, digital microscope and energy dispersive X-ray analysis. The link between laser ablation conditions, particle formation and elemental fractionation was discussed. |
