Experimentally determined values for zeta increased at 0.39% per °C, a rate that is about four to five times smaller than reported previously. Experimentally determined values of zeta were directly proportional to the absolute temperature although values were also influenced slightly by changes to the dielectric constant. It was found that the effective charge density at the inner surface of the capillary was independent of temperature. 2006-02 Article PeerReviewed application/pdf http://eprints.utas.edu.au/3677/1/RMG15.pdf http://dx.doi.org/10.1002/elps.200500566 Evenhuis, CJ and Guijt, RM and Macka, M and Marriott, PJ and Haddad, PR (2006) Variation of zeta-potential with temperature in fused-silica capillaries used for capillary electrophoresis.
