## streaming potential difference (streaming potential)

https://doi.org/10.1351/goldbook.S06050
The potential difference $$E_{\mathrm{st}}$$ or $$E$$ at zero current caused by the flow of liquid under a pressure @G02669@ through a @MT06878@, plug or capillary. Identical electrodes must be used on both sides of the @MT06878@, plug, etc. $$E$$ is positive if the higher potential is on the high pressure side.
