JN01A High-Concentration Zeta Potential Electrophoresis Analyzer

Product Introduction

The JN01A High-Concentration Zeta Potential Electrophoresis Analyzer is designed to measure the Zeta potential of particles in high-concentration and concentrated dispersion systems. Unlike measurement approaches intended primarily for dilute samples, the JN01A is developed for suspensions closer to actual industrial operating conditions, including drilling mud, industrial wastewater, and papermaking systems.

Its continuously rotating sample cell helps reduce particle sedimentation during measurement. The sample cell also accommodates both large and small particles, helping provide a more representative assessment of the overall dispersion rather than relying only on the behavior of easily observed fine particles.

The JN01A is suitable for industrial process research, quality control, and teaching applications in petrochemicals, wastewater treatment, papermaking, cosmetics, mineral processing, healthcare, construction materials, ultrafine materials, and environmental protection.

Performance Features

• High-concentration sample measurement: Designed for concentrated dispersions and suspension systems closer to real industrial operating conditions.

• Continuously rotating sample cell: Keeps the sample moving during measurement to help reduce particle sedimentation.

•  Representative particle assessment: Takes account of both large and small particles in the sample cell.

• Reduced fine-particle observation bias: Helps address measurement limitations associated with sedimentation of larger particles and observation of only smaller particles.

• Industrial application suitability: Particularly relevant to drilling mud, industrial wastewater, paper pulp, and coating preparation.

•  Process optimization support: Zeta potential measurements help evaluate particle surface charge and manage dispersion behavior in industrial processes.

Working Principle

The JN01A uses an electrophoresis-based approach to determine the Zeta potential of particles in concentrated dispersion systems.

When an electric field is applied, charged particles move through the liquid medium according to their electrophoretic behavior. The instrument evaluates this behavior to determine the Zeta potential, which provides information about particle surface charge and dispersion characteristics.

During measurement, the sample cell rotates continuously to help limit particle settling. This is particularly useful for concentrated samples containing particles of different sizes, where sedimentation can affect measurement representativeness.
