  • Application Area: 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. "

Review date: 12 Oct 2015 | SurPASS™ 3: A New Level of Surface Charge Analysis

SurPASS™ 3 offers a new level of surface charge analysis. The instrument determines the zeta potential which is related to the surface charge of a solid material in contact with an aqueous solution. Its precision and easy handling makes it the perfect measurement instrument for everyone in this field.

By measuring the movement of a fluid in relation to the solid material SurPASS™ 3 determines the streaming potential from which the zeta potential is directly calculated. The movement of the fluid is free of vibration, which guarantees highly precise results. SurPASS™ 3 combines a proprietary method for liquid transport with a higher time resolution for collecting measuring data.

The accompanying software measures and visualizes the surface charge and allows the determination of the isoelectric point with just one mouse-click. Easy handling is also guaranteed with the plug-in sample holder.

The instrument is designed for different types of operations – from scientific to industrial. New applications in the fields of membranes, biomaterials and semiconductors are possible due to the extended capability for higher applicable pressure.
