• Description: Different techniques of pellet preparation were compared for powdered samples representing geological (soils) and biological (infant formula) materials. The most important factors such as harndess, cohesion and homogeneity of prepared targets were studied. UV and IR laser ablation of prepared pellets with 266 nm and 1064 nm Q-switched Nd:YAG laser was investigated. The elemental analysis using LA-ICP-OES was performed and the precision and accuracy of created methods were compared.
