CONTAINER FOR PRETREATMENT IN ANALYSIS OF ELEMENT AND ELEMENTAL ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a container for the pretreatment in the analysis of an element superior in heat resistance and chemical resistance, such as acid resistance or the like, optimum with respect to heat treatment and capable of smoothly performing the transfer and replacement of the solution in the container, and to provide an elemental analysis method that uses it.;SOLUTION: The container for the pretreatment in the analysis of the element is used, when at least a measuring sample is dissolved in a solvent. The surface roughness of the inner surface of the container is Ra≤5 μm, Rmax≤20 μm, and the material of the container is ceramic.;COPYRIGHT: (C)2006,JPO&NCIPI
