This paper describes a versatile, light weight, and portable chamber dedicated to the transfer of electrodes from ultra-high vacuum (UHV) to atmospheric pressure and the liquid phase. This chamber can be connected to a liquid-phase reaction cell to perform electrochemical measurements and transfer back the electrode to the UHV environment. The experimental set-up can also be turned in order to make the electrode the bottom of the electrochemical cell. The validity and the efficiency of the experimental set-up were tested with a Pt(111) surface that provides unique electrochemical features in acidic sulphate-containing solution. This transfer chamber concept provides the surface science community with a new and versatile tool, complementary to existing systems, which allows fast electrolyte purging or electrochemical measurements under well-controlled mass transport conditions.
本文描述了一种多功能、轻质且便携的腔室，专门用于将电极从超高真空（UHV）转移到大气压和液相环境。该腔室可连接到液相反应池以进行电化学测量，并将电极转移回超高真空环境。实验装置还可以旋转，使电极位于电化学池底部。使用在含酸性硫酸盐溶液中具有独特电化学特性的Pt(111)表面对实验装置的有效性和效率进行了测试。这种转移腔室概念为表面科学界提供了一种新的多功能工具，是对现有系统的补充，它能够在良好控制的传质条件下实现快速电解液吹扫或电化学测量。
