Zeta potential and particle size analyzer is an advanced instrument widely used in the field of particulate matter research.
This article will provide an in-depth analysis of the instrument and cover some related content to make the article richer.
1.Introduction: Zeta potential and particle size analyzer is mainly used to measure the electromotive force and size distribution of particulate matter.
It analyzes the surface charge properties of particles by suspending the sample in solution and applying an electric field.
The size distribution of particles can be measured using the principle of light scattering, which allows for an accurate assessment of the morphology, concentration, and stability of the particles.
2.How it works: Zeta potential refers to the ability of a particle surface to be charged, which can be used to evaluate the interaction forces between particles.
The zeta potential is calculated by using a pair of electrodes to contact the sample suspension and an electric field is applied to measure the migration rate of the particles under the action of the electric field.
By analyzing the value of the zeta potential, it is possible to infer the charged state and stability of the particle surface.
3.In addition to the measurement of zeta potential, the instrument can also evaluate the size distribution of particles by light scattering technology.
Light scattering uses a laser beam to irradiate a sample and measure the angle and intensity of the scattered light to obtain information about the size and concentration of the particles.
By analyzing the scattered light intensity at different angles, the size distribution curve of the particles can be obtained, and the particle size characteristics of the sample can be further understood.
4.ApplicationsZeta potential and particle size analyzers are widely used in many fields.
In the chemical industry, the instrument can be used to evaluate the dispersion of particulate matter to optimize the quality of products such as coatings, inks, and pigments.
In pharmaceutical research and the pharmaceutical industry, instruments are often used to study the stability of particulate drug delivery systems and nanomedicines.
In the field of environment and food safety, the instrument can be used to detect the size and stability of contaminants and microorganisms, helping to protect public health.
5.Further expanding the basic functionality of zeta potential and particle size analyzers, some advanced models also offer additional functions such as color, rheological properties, and conductivity.
These additional features allow the instrument to be used in a wider range of applications.
Some vendors also offer data analysis software that allows the results to be further processed to help users better understand the characteristics of the sample.
As an important tool for particulate matter research, the zeta potential and particle size analyzer can evaluate the surface charge status and size characteristics of particulate matter by measuring the zeta potential and particle size distribution.
The instrument plays an important role in many fields such as chemistry, medicine, and environment, and has certain scalability and data analysis functions.
