Method for the sample preparation of liquid or paste-like substances for measurements with X-ray fluorescence and sample bodies suited therefor

摘要

A process for preparing, and an analysis of, liquid or pasty substances not consisting exclusively of volatile constituents and a sample body for use in such a process. The substance to be analyzed is applied to a rigid sample body with at least one flat and smooth analysis surface formed of an absorptive material. The substance is adsorbed and absorbed by the sample body, and is analyzed using an X-ray fluorescence analysis.
