On the possibility of using «Grand-Potok» unit with MAÉS analyzer for analysis of solutions and water aerosols

Abstract

Modernization of «Grand-Potok» atomic emission complex with MAÉS analyzer («VMK-Optoélektronika», Novosibirsk, Russia) first designed for analysis of powder samples is considered in view of the possibility of analysis of solutions and aqueous aerosols avoiding changes in the sample injection. It is shown that upgraded input system equipped with a nebulizer provides determination of platinum and gold in aqueous solutions with detection limits 1 – 5 ppm. Analysis of water aerosols with silver nanoparticles by scintillation method revealed the possibility of detecting separate silver nanoparticles about 200 nm and more. Thus we have demonstrated that modernization of the complex provides the possibility for analysis of solutions and aerosols obtained upon electro-spark and laser ablation of various materials, as well as for microanalysis of the objects.
