Anton Paar launches SurPASS™3 – another milestone in surface charge analysis

SurPASS™3 determines the zeta potential at the surface of a macroscopic solid in contact with an aqueous solution. The compact instrument design with plug-in sample holders gives easy access to material surface charge to everyone – from scientists in academia to technicians in industrial labs.

Rugged and compact design with small footprint
The laboratory space occupied by SurPASS™3 is significantly reduced as compared to previous models of streaming potential analysers.

 

The compact instrument design does not contain any moving parts, unnecessary tubing or cables, which may be subject to measuring artifacts. SurPASS™3 keeps the promise of a real plug-and-measure instrument: simply plug in the measuring cell and hit the START button.

Fast and reliable analysis of surface zeta potential

The enhanced SurPASS™3 principle gives access to zeta potential data in less than 3 minutes. The high time resolution for data acquisition and the extremely sensitive measurement of streaming potential improve the reliability and reproducibility of zeta potential even in the range below 3 mV.

pH scan and isoelectric point by the push of a button
The operating software of SurPASS™3 offers the selection of single zeta potential data, the analysis of the surface isoelectric point, or a full pH scan. The operation modes are complemented by the investigation of solute effects on the solid surface to characterize adsorption and desorption processes.

Functional measuring cells for increased sample throughput
Independent of sample geometry, size and origin, SurPASS™3 determines reliable and reproducible zeta potential values. Elaborate measuring cells for individual sample materials give you the utmost flexibility for your quality control and investigations. Mounting sample holders was never that easy. The measuring cell in use is automatically detected by the SurPASS™3 software.

Lean software interface with clear display of measuring data
The lean structure of the SurPASS™3 operating software helps you to focus on the important task: the analysis of the surface zeta potential of your sample. The software still remains intuitive even if you do not care much about the physical background of the surface zeta potential. Together with the enhanced measuring principle of SurPASS™3, the software facilitates the fastest route to the zeta potential of macroscopic solids.
