Effects of Thermal Treatment on Laser Generated Aerosols using LA-ETV-ICP-MS

Original language description

Aerosol particle size distribution is generally known to be critical for complete sample vaporization upon introduction into an ICP discharge. Particle size dependent composition of laser-produced aerosols has been proved to be responsible for ICP-induced elemental fractionation. The modification of the particle size distribution has been studied based on heating a laser-generated aerosol by means of an electrothermal vaporizer (ETV) installed between an ablation cell and an ICP torch. Overall, 21 singlemetal targets were ablated and heated up by the ETV prior to entering into the ICP discharge. Brass and steel samples were also studied as multielement samples. The aim of this study was a) to modify the particle size distribution towards reduced diameters b) to determine the elemental dependence of the vaporization process, and c) to determine elementdependent laser-induced phase separation into different particle sizes. It was observed that the vaporization depended on melting points
