Abstract
We report here the first fully automated capillary electrophoresis (CE) system that can be operated underwater. The system performs sample acquisition and analysis by coupling CE to contactless conductivity detection. Using 5 M acetic acid as the background electrolyte (BGE), inorganic cations and amino acids at concentrations as low as 5.2 μM can be separated and identified. This technology could be augmented to include a variety of other detection modes. This system serves as an early prototype for potential future underwater explorers on ocean worlds of the outer solar system such as Europa or Enceladus. This work documents the first step in the development of this general-purpose technology platform.
