| The application of the membrane nanotechnology for obtaining super-pure (up to 8N) non-crystalizing overcooled big mass (>30 g) gallium melt by refinement of commercially available 5N÷6N purity gallium, give us opportunity to obtain unique samples in order to develop a new methodology of analytical sample preparation for GDMS analysis, which excludes artifacts tied to impurity atoms segregation on the analytical Ga sample surfaces. Using comparison of results of GDMS analysis of samples prepared by the existed method and by the new method from the essays of initial 6N commercial gallium and super-pure (7N+) gallium obtained by the membrane purification from the initial gallium, we have determined the most reliable analytic procedure for the final check on the production and certification of super-pure (up to 8N) gallium. |
