A particle size analyzer is an instrument used to measure the size of particles, and it has a wide range of applications in many fields.
This article will provide an in-depth analysis of the working principle, classification, benefits, and application areas of particle size analysis instruments.
1.Working principleParticle size analysis instruments mainly determine the particle size by measuring the scattering, astigmatism, light transmission and other phenomena of particles in liquids or gases.
One of the most commonly used techniques is laser light scattering, which uses a laser beam to irradiate particles and calculates particle size by detecting the intensity and angle of the scattered light.
2.Classification particle size analyzers can be classified according to different measuring principles.
Common classifications include dynamic light scattering, static light scattering, laser particle counting, etc.
Each classification method has its scope of application and advantages and disadvantages.
3.Advantages: The particle size analysis instrument has the following advantages: (1) High resolution: it can measure the size of particles at the micron and even nanometer level, with high accuracy.
2) High sensitivity: It can quickly and accurately detect the size change of particles.
3) Non-destructive: no damage or contamination will be caused to the sample during the measurement.
4) High efficiency: It can quickly complete the sample analysis and improve the work efficiency.
4.Application FieldParticle size analysis instruments have a wide range of applications in many fields, including but not limited to: (1) Materials science: used to study particle size distribution and size control of nanomaterials, coatings, ceramics, etc.
2) Pharmacy: used for the research, quality control and efficacy evaluation of drug particles.
3) Environmental monitoring: used for the monitoring and analysis of particulate pollutants in the atmosphere and water.
4) Biomedicine: used for the research and analysis of particles in biological fields such as cytology, pharmaceutical carriers, proteins, etc.
5) Food industry: used for particulate analysis in the fields of food additives and dairy products.
Particle size analyzers are an important scientific tool that can help researchers gain insight into the properties and behavior of substances by measuring particle size.
It has a wide range of applications in materials science, pharmacy, environmental monitoring, biomedicine, and the food industry.
With the continuous advancement of technology, particle size analysis instruments will further improve the efficiency and accuracy of analysis, and provide better support for research in all walks of life.
