Hi! I want to ask about the density calculation of a particle or particles. I have read in Allen books to calculate the density of particles by using dispersant and go to m/v with addition calculation. I dont want to use dispersant because unreachable and difficulties to purchase dispersant here. Let me know if anyone has the procedure. I want to calculate organic particle (powder from natural substance). It has certain mesh number of 140 mesh
The particle density of a substance is determined by dividing its mass by the volume it occupies. In the pharmaceutical industry, however, direct density measurement is commonly employed as the mixture column is dependent on the air gaps between the particles.
Dear - I am adding the official OECD 109 protocol on the determination of solids and liquids. You indicate a mesh of 140 mesh which seems to indicate that the density is function of the particle size (which is usually the case). This protocol is intended for most of the chemical substances.
Vikram Alexander do you have number of particles from DLS if yes then you can calculate the particle number density by dividing the numbers obtained by the volume of the particle. hope it helps
