Surface Zeta Potential Cell - Malvern Zetasizer Nano Series Accessories Manual

Surface zeta
potential cell
Introduction
This chapter gives an overview of the Zetasizer Nano cell for measuring surface
zeta potential. It describes how to use, insert and clean the cell to ensure reliable
and consistent measurements.
The Surface zeta potential (SZP) cell is intended for the measurement of the
zeta potential at the surface of a flat material in an aqueous environment. The cell is
a dip cell type device and can be used with 1ml cell DTS0012 and PCS1115. It is
incompatible with the MPT-2 Titrator.
The cell consists of a height adjustable sample barrel , in which the sample is
glued onto a sample holder  and held between two palladium electrodes . A
series of zeta potential measurements are then performed in a conventional cuvette
, with the measurement position within the cell controlled by rotating the cell
cap  which adjusts the height of the sample barrel.
