Mesh is the unit to measure the pore size of a sieve, defined as the number of pores per inch in a sieve. The larger the mesh, the smaller the pores. Because the standard in different countries varies...

(1) Instrument: whether the laser, detector, signal transmission system, control system, sampling system, and software work fine.(2) Operation process: background, shading, software parameters, medium...

For particle sizing instruments, the evaluation of reproducibility is important in several aspects:(1) to understand the long-term stability of the instrument;(2) to evaluate the stability of the samp...

Repeatability and reproducibility are two important factors for particle size analysis. So we must know what is reproducibility? What is the difference between repeatability and reproducibility?Reprod...

Repeatability is important evidence used to evaluate the current status of the instrument. Good repeatability indicates that all parts of the instrument, including laser, detector, signal transmission...

Several methods are commonly used to measure particle size. These methods include laser diffraction (mm, μm, nm), dynamic light scattering (nm), dynamic and static microscopic imaging (μm, size and ...

D50 is the corresponding particle size when the cumulative percentage reaches 50%. D50 is also called as the median particle diameter or median particle size. For example, for a powder sample with D50...

Particle size is one of the main characteristics of powder materials. It is associated with parameters such as cement reactions in water, attaching strength and coverage of coatings, capacity of lithi...

Particle size indicates how small (or big) a particle is. The unit is usually μm or nm. Mm could also be used for certain fields where the particles are relatively big. Diameter is usually used to de...
