Ultrasonic electroacoustic Zeta potential analyzerIt is an advanced instrument based on electroacoustic oscillation technology, which can directly measure the Zeta potential of high concentration samples (such as paste, gel, cement, etc.) without dilution or complex pretreatment. The core principle is to excite particle motion through a high-frequency electric field to generate sound waves, analyze the sound wave signal to calculate the dynamic mobility, and then derive the Zeta potential.

The Zeta potential analyzer using ultrasonic electro acoustic method adopts specialized electric acoustic oscillation technology, which can achieve extraordinary electric measurement results, thus avoiding many limitations and restrictions of traditional microelectrophoresis technology.

Daily maintenance:

Cleaning and Inspection:

After daily use, wipe the surface of the instrument and the contact area of the probe with a dust-free soft cloth to avoid residual coupling agent.

Check if the power cord and electrode connection wire are loose, and ensure that the grounding resistance is ≤ 40 Ω.

Environmental control:

Maintain stable laboratory temperature and humidity (recommended at 20-25 ℃) to avoid temperature fluctuations affecting measurement accuracy.

Regularly clean the ventilation filter to prevent dust accumulation and poor heat dissipation.

Common troubleshooting:

Measurement instability:

Possible reasons: high/low sample concentration, electrode contamination.

Solution: Adjust the sample concentration to the recommended range (usually 0.1%~60%), clean or replace the electrode.

Abnormal temperature:

Possible reasons: Temperature control system malfunction or environmental temperature fluctuations.

Solution: Check the constant temperature module to ensure temperature balance between the sample and the instrument.
