Concept of FST Method
FST – Electrophoretic mobility measurement of concentrated suspension using Forward Scattering through Transparent electrode.
By conventional methods, scattered light from a concentrated suspension can not be measured correctly due to multiple scattering (A). The FST method detects the scattered light from particles through a transparent electrode. The optical path length is minimized to reduce the effects of multiple scattering. Thus, the NanoPlus can perform a zeta potential measurement of a concentrated suspension with a high degree of accuracy (B).
