Term: sedimentation field strength https://doi.org/10.1351/goldbook.S05537 Definition: The potential difference E sed per unit length in a sedimentation or centrifugation cell. As the contributions of the interfacial potential differences at the electrodes are not included in E sed this quantity, although theoretically important, is not accessible to measurement.
