Nanomaterials analysis and research droplets angle wholesale nanoparticles often encountered particle size generally refers to nanometer scale (1 ~ 100nm) of the ultrafine particles. Because the particle size of such materials for nanoscale, itself has a small effect, quantum size effect, surface effect and macroscopic quantum tunneling effect, so it has many conventional materials do not have the characteristics, catalysis, nonlinear optics, magnetic , aspects of medicine and new materials has broad application prospects. Therefore, the particle size of nanomaterials, distribution, has an important influence on the performance of the medium dispersion properties and morphology of the secondary particles assemble nanomaterials, therefore, particle size analysis of nanomaterials is an important aspect of nanomaterials research. Also because of the nature and importance of nanomaterials, to promote the development and characterization of particle size analysis methods and techniques, particle size analysis of nanomaterials has become an important area of ??modern particle size analysis. Currently, nanomaterials particle size analysis method and apparatus for many types of water droplets corner, but due to a variety of analytical methods and instrumentation design for the system to be analyzed has some relevance, analysis principles and methods used vary, therefore, to choose the right analytical methods and analytical instruments is very important. And because the physical basis of a variety of different methods of particle size analysis, the physical meaning of the same sample obtained with different methods of measurement of particle size and even particle size is also different. In addition, the use of different particle size analysis methods are also different. If the system of analytical instruments and test results do not accurately understand and grasp, the resulting molecules tend to have larger differences in actual results, not scientific and representative. Therefore, the angle of water droplets plant sales, according to the measured object, the measurement method of measuring accuracy and measurement accuracy choice is very important and necessary. Material particle size analysis method to have many, has developed and produced more than 200 kinds of analysis based on various works droplets angle measuring device where cheap, and there are always new particle size measurement methods and instruments developed. Although a variety of methods of particle size analysis, basically can be summarized as the following method. The traditional methods of measuring particle sieving, microscopy, sedimentation, electric induction method, a method developed in recent years with a laser diffraction method, laser light scattering, photon correlation spectroscopy, electron microscopy image analysis method, based on the particle-step Brownian motion of the particle size and mass measurement method. Wherein the laser scattering method and photon correlation spectroscopy method because of high speed, wide measurement range, the data is reliable, reproducible, high degree of automation, ease of on-line measurement, etc. are widely used.
