System Zeta Potential

Purpose
All Particles present in liquid normally take on electrostatic surface charges that generate a charge cloud centered on the particles. The total potential different present in this charge cloud is termed equilibrium potential. The zeta potential is associated with the outer diffuse double layer, which is may be deformed as the particle move. This double layer is largely responsible for the stability of stock suspension or slurries and pay a decisive role in papermaking operations.
Principle
The zeta potential is determined by measuring the velocity of motion of the charged particles in an electric field.
How to use
CLEANING THE SAMPLE CELL AND ELECTRODES
Clean the Sample cell before measurement
After measurement, Deionized water must fill in to the sample cell , if the type of sample cell are same, just clean with deionized water and electrodes
Setting up the connection, connect the measurement with in vacuum pump and vacuum hose , Connect vacuum pump cable, electrodes cable to the measurement ( with same color code cable). Turn on the power
PROCEDURE
Fill 500 ml sample solution in to beaker sample
Before switch on, make sure vacuum hand valve on off position
Switch SZP 06, System will operate it self, put in sample beaker
Switch on the vacuum pump, press “P”
Slowly open up the vacuum hand valve, make sure no bubble air, if any bubble air stop measurement , and press “R” for reset system
Wait until1minutes and then press START, watch on P min(0.2) and P max(0.4)
Measurement procedure, System will count potential (30 second), and then it will stop automatically
When sample conductivity measurement finish, vacuum pump will shut down automatically.
Value zeta potential will show on the display
Clean up sample cell for next measurement
