BS ISO 13099-2:2012

This standard BS ISO 13099-2:2012 Colloidal systems. Methods for zetapotential determination is classified in these ICS categories:

• 19.120 Particle size analysis. Sieving

This part of ISO 13099 specifies two methods of measurement of electrophoretic mobility of particles suspended in a liquid: video microscopy and electrophoretic light-scattering. Estimation of surface charge and determination of zeta-potential can be achieved from measured electrophoretic mobility using proper theoretical models, which are described in detail in ISO 13099-1.
