SurPASS™ 3: A New Level of Surface Charge Analysis
The SurPASS 3 series features fully automated zeta potential analysis of macroscopic solids under real-life conditions. As electrokinetic analyzers, they employ the classic streaming potential and streaming current method for a direct analysis of the surface zeta potential. The zeta potential is related to the surface charge at a solid/liquid interface and is a key parameter for understanding surface properties and developing…

Very robust machines that deliver.
Charge determination for surfaces
The set-up is easy to use and delivers good and reproducible results. I have been very happy with it. One issue that can be problematic is contamination. Cleaning the set-up can be very time-intensive. Be careful in particular with surfactants. The manufacturer has been very helpful in trying to solve such problems and only in cases where they did not have the problem themselves, they did not have a quick answer. But would always try to help. They are also very good in bringing people together. I am still happy with this and would certainly buy it again.

Streaming Potential
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.
