streaming potential difference (streaming potential)

https://doi.org/10.1351/goldbook.S06050
The potential difference Est or E at zero current caused by the flow of liquid under a pressure
gradient
through a
membrane
, plug or capillary. Identical electrodes must be used on both sides of the
membrane
, plug, etc. E is positive if the higher potential is on the high pressure side.
