PANORAMIC ANALYSIS OF IMPURITY CONTENTS IN DIATOMITE, DURALUMIN, STAINLESS STEEL, COPPER AND NICKEL

In order to offer the concerned data of matrix, container and plating materials in NDA standards and set up a panoramic analysis method about impurity element contents, the impurity element contents in diatomite, duralumin, stainless steel, copper and nicker are analyzed by spark source mass spectrometry. About 60 impurity element contents in each sample with semi quantitative analysis are obtanined.
