MÜTEK SZP-06 SYSTEM ZETA POTENTIAL
... KNOWS WHAT'S ON YOUR FIBER
The MütekSZP-06 System Zeta Potential detects the surface charge of fibers and fillers. Measuring samples before and after contact with a chemical additive evaluates the efficiency, for example, of a starch or a wet strength agent in the papermaking process. The SZP is becoming a standard tool especially as process samples can be taken as they are, and do not have to be changed for e.g. electrophoresis.
By using the tailor-made software Mütek ChargeView results obtained by the SZP-06 can be transferred in a database to administrate them and also compare them with measurements of the Mütek PCD-04 Travel.
Measuring Principle
The centerpiece of the SZP is a plastic measuring cell with ring and screen electrodes. A fiber sample is drawn into the cell by applying a vacuum. At the screen electrode a fiber plug forms. A pulsating vacuum causes the aqueous phase to oscillate through the plug, thus shearing off the counterions and generating a streaming potential. The zeta potential is calculated by using the measured streaming potential, conductivity, and the pressure differential.
For pigment measurements, the SZP-06 is offered with a special set of electrodes.
