New ISO Standards for Zeta Potential Analysis
Apr 03 2012
Author: Mark Bumiller on behalf of Horiba France SAS
Zeta potential is a measure of the charge on a particle surface in a specific liquid medium. With growing interest in nanotechnology and protein research, zeta potential analysis has become an increasingly important analytical technique. Since few chemists posses an extensive background in zeta potential theory or practice, an ISO working group was formed to create new several new standards on this subject. These new ISO standards [1, 2] provide excellent background material and advice to chemists new to the analysis of zeta potential.
