In granulometry, the particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. [1] Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size . The particle size method is discussed in detail to ensure an in-depth understanding of particle size distribution and said method can be used for particle size determination of Lumefantrine.
