Anton Paar's SurPASS 3 is a milestone in surface charge analysis for the company.
The compact instrument determines the zeta potential at the surface of a macroscopic solid in contact with an aqueous solution.
Plug-in sample holders provide easy access to material surface charge.
SurPASS 3 is part of Anton Paar's efforts to commercialise the surface zeta potential method for material characterisation.
As well as being compact, it features a proprietary method for liquid transport with a higher time resolution for collecting measuring data.
This enables a better sensitivity for the zeta potential analysis at a significantly shorter measuring time.
For the first time, determination of the isoelectric point is offered at a single click.
The measuring cell in use is automatically detected by the instrument software.
With the extension to higher applicable pressure SurPASS 3 opens up new applications in the fields of membranes, biomaterials or semiconductors.
