INVESTIGATION INTO THE CHEMICAL COMPOSITION OF THE COATING MATERIAL FOR COLOR TV BRAUN TUBE USING GDMS

Abstract

The chemical composition of the coating material used for color TV Braun tube has been investigated using a GDMS incorporated with the dual mode ion detector system. The major, minor and trace constituents of the material studied could be determined in the same analytical cycle. Zn, S and O are found to be the major components and Si, C, Eu and Ba are found to exist as minor ones. As trace elements, Sm, Sr, Y, W and etc. were determined. The data obtained by means of GDMS were compared with those obtained using CHN analyzer, ICP, PIXE, XRF and AAS.
