The surface charge of a solid material influences the interaction with its surroundings, which makes this property decisive for many applications in technical fields and life sciences. The knowledge of surface charge is therefore of paramount importance to take influence on the solid surface behavior.
Quantitative information is available in short time with the SurPASS electrokinetic analyzer.
The enormous flexibility of the SurPASS measuring cells enables the zeta potential analysis of solids of almost any size and shape. The range of applications starts with powder samples of particle size from some tenth of microns to more than one millimeter. The same measuring cell accomodates fibre material of different origin like glass, carbon or textile fibres. The step towards samples with planar surfaces only requires the exchange of the measuring cell.
