Concentration method of liquid specimen and trace element analysis method using same

摘要

This invention enables a high sensitivity analysis for a trace element contained in a liquid specimen.;In this invention, a liquid specimen, which is used in an element analyzer having an irradiation source with energy of 1.24 eV or higher, is dropped onto a thin film of a water-repellent resin or an organic thin film coated with a water-repellent material, and concentrated by evaporation of a solvent.
