PURPOSE: To enable highly accurate instrumental analysis quickly and easily with a simple solidification of a powder sample, by placing a fixed amount of a powder sample for analysis on a ductile substrate to press the sample intensely through a pressure disc having a mirror-finished surface.
CONSTITUTION: A pressure plate 4 is mounted on the top surface of a lower pressure disc 3 of a press machine 2 and a ductile substrate 5 is placed thereon. The ductile substrate 5 herein used requires rich ductility enough to withstand a compressing force and is optimally an aluminum plate. Then, a powder sample 1 for analysis is placed on the top of the ductile substrate 5 and a pressure plate 6 is put thereon with the surface thereof ground mirror-finish. Then, a compression load is applied with a press machine 2 to press the ductile substrate 5 and the powder sample 1 for analysis intensely through two pressure plates 4 and 6. Thus, the powder sample 1 is formed smoothly integral with an aluminum plate 5 as ductile substrate and moreover, the powder surface 1a is mirror- finished thereby obtaining a solidified sample 7 ideal for instrumental analysis.
