| Abstract: | In this paper, the cover function of electrode with an outer cover is discussed. Volatile elements have high sensitivity in the method of reference1], because the temperature of electrode with sample is reduced by the outer cover, and the diffusion loss of atoms on the electrode with sample is not reduced by the outer cover. When the vaporization of volatile elements is rapid, their determination sensitivity is worsened greatly because the effectively entered vapour is reduced. |
