"This machine is working very well. Even on long-term it gives reliable results. We have been reproducing data for a long time. No problem. As soon as a specifically adsorbing chemical comes into the system, it can be difficult to remove it. We have had problems with injections of nano-particles or surfactants. We found them hard to remove and Anton Paar did not have a solution to that. Finally we managed to get rid of the contaminations but it costs a lot of time testing. Also using Bromide with the silver chloride electrodes was more of a problem than what Anton Paar thought. Overall this machine is very good value for the money invested. "
Use the SurPASS electrokinetic analyzer to investigate the zeta potential of macroscopic solids based on the streaming potential and streaming current method. The zeta potential is related to the surface charge at a solid/liquid interface and is a powerful indicator for the surface chemistry (pH titration) and liquid-on-solid surface adsorption processes. The SurPASS helps you to understand and improve surface properties and to develop new specialized materials.
