The microelectrophoresis (Zeta potential meter) developed and produced by Shanghai Zhongchen Digital Technology Equipment Co., Ltd. has been available for 26 yearsIt is a project supported by the National Innovation Fund without compensation. This instrument can be used to determine the solid-liquid interfacial electrical properties (zeta potential) of dispersed system particles, as well as to measure the interfacial electrical properties of emulsion droplets. It can also be used to determine the isoelectric point and study the mechanism of interfacial reaction processes. Measuring the Zeta potential of particles to determine their isoelectric point is an important method for understanding the surface electrical properties of particles, and it is also an important means in particle surface treatment. Compared with other similar instruments at home and abroad, it has significant * performance. It can be widely used in industries such as cosmetics, mineral processing, papermaking, medical and health care, building materials, ultrafine materials, environmental protection, marine chemistry, etc. It is also one of the important teaching instruments for majors such as chemistry, chemical engineering, medicine, and building materials.
The national standard "General rules for zeta potential analysis electrophoresis of colloidal particles" has been released, with the standard number GB/T 32668-2016. This national standard came into effect on November 1, 2016. The microelectrophoresis method is based on the JS94 series microelectrophoresis (zeta potential analyzer) developed and produced by Shanghai Zhongchen Digital Technology Equipment Co., Ltd. The software interface of the JS94 series microelectrophoresis (zeta potential analyzer) is shown in the image on page 16 of the standard.
