Particle size analysis has established huge interest due to its significance in Industries Particle size analysis and research is the research of particles to learn about their sizes. These can be solid, liquid or gaseous. In its most general appearance, particle size analysis is considered taking a particle to be circular in shape. For such particles, the size of the particle would be its thickness. On the other hand, in real study, it is uncommon to find completely spherical particles and these could be of any shape and size. In that condition, it is impossible to identify their size as the thickness of the particle. To resolve this answer, scientists have found out various ways to find out the size of non-spherical particles. All of these creations are based on the original size definition of a spherical particle. The most important techniques of finding size of non- spherical particles include: Volume based size in which the particle size equals the thickness of a spherical particle of the same size. Weight based, in which the particle size equals the thickness of a spherical particle of the same weight. With so many dissimilar likely definitions and still added numbers of different shapes, study and sizing of particles is a hard duty, especially with sizes under a micrometer. As an outcome, scientists have tried out diverse ways for the precise measurement of sizes. These ways include light-based methods, ultrasound, electric field, gravity, and centrifugation-based process. Zeta potential is a parameter characterizing electrochemical equilibrium on interfaces. It depends on the properties of liquid as well as on properties of the surface. Zeta potential analyzer is the instrument to measure zeta potential from the parameters and requires a correct theory.
