本文研究了一种电化学电池设计，允许清洁转移的电极到超高真空表面分析室。通过使用定量俄歇电子能谱（AES）应用于来自HF-NaF水溶液电解质的非挥发性钠残留物，确定在浮现后保留在表面上的电解质厚度的数量级。发现没有氟俄歇信号观察到正确emersed电极;较高水平的钠，有时氟观察到在毛细管分离点或当不适当的排水左可见液滴在interelectrode间隙;并试图涌现晶体下降的反参考组件垂直远离它留下较大的电解液滴在表面上。
This paper examines an electrochemical cell designed to allow the clean transfer of an electrode to a ultra-high vacuum surface analytical chamber. Determines the order of magnitude of the thickness of electrolyte remaining on the surface after emersion by using quantitative Auger electron spectroscopy (AES) applied to the non-volatile sodium residue from a HF-NaF aqueous electrolyte. Finds that no fluorine Auger signals were observed on properly emersed electrodes; higher levels of sodium and sometimes fluorine were observed in the capillary separation spot or when improper draining left visible droplets in the interelectrode gap; and attempts to emerse the crystal by dropping the counter-reference assembly vertically away from it left larger electrolyte drops on the surface.
