High concentration Zeta particle size analyzer assists in the production and debugging of grinding fluid

1. The role of Zeta potential analysis in production

ZETA potential refers to the potential of the shear plane, also known as electromotive potential or zeta potential, and is an important indicator for characterizing the stability of colloidal dispersion systems. The significance of Zeta potential lies in the positive correlation between its absolute value and the stability of the detection object. Zeta potential is a measure of the strength of mutual repulsion or attraction between particles. To some extent, the smaller the molecule or dispersed particle, the higher the absolute value of Zeta potential, and the more stable the system. On the contrary, the lower the absolute value of Zeta potential, the more likely molecules are to condense or coalesce. Zeta potential measurement technology has been widely applied in various fields of industry and scientific research, such as ceramic production. We need to measure the Zeta potential of ceramic slurry to investigate its storage stability; In the field of biopharmaceuticals, we need to test the Zeta potential of protein solutions to minimize the aggregation of protein macromolecules; In the field of water treatment, the opposite is true. It is necessary to add coagulants and adjust their potential to near the isoelectric point, making it easier to flocculate and precipitate in order to remove particle impurities from the water. Since Zeta potential is so important, how can we obtain accurate Zeta potential data for a suspension system? Yinhuang Technology will guide you through the specific process of Zeta potential analysis using the high concentration Zeta potential analyzer from the MAS series in the United States.

2. Product Introduction

2.1 Introduction to MAS Company in the United States

MAS (Mass Applied Sciences) has a history of more than 30 years since its establishment in the United States. It is a research and production enterprise specializing in the development and production of particle size and Zeta potential analyzers based on ultrasonic electroacoustic principles. The nano particle size and Zeta potential analyzer series products developed and produced by the company have solved the difficult problem of nano particle size detection that cannot be overcome by optical methods on the market. Optical methods require testing the particle size and zeta potential of the sample after dilution, and cannot provide accurate particle size distribution for complex systems. At present, MAS Corporation's nanoparticle size and Zeta potential analyzer series mainly include Zeta-APS, APS-100, Zeta Finder ZF400, ZetaAcoustic ZA500, CHDF-3000/4000, which can provide professional particle size and Zeta potential solutions for various industries.
