Question

The type of particle diameter that is obtained by microscope method of evaluation is?

Answer 1

Answer:

The optical microscope method is applicable to particles in the size range 0.8–150 µm, and down to 0.001 µm using electron microscopy.

Explanation:

Answer 2

Pharmaceutical Physics

The type of particle diameter that is obtained by microscope method evaluation is Projected.

• The projected area diameter is the diameter of a sphere having the same projected area as the particle.
• Optical microscopy is  used for the characterization of particles whose size is ranging between 0.25 µm and  100 µm, and in this particle size is expressed as projected diameter.
• Particle sizes are measured in microns.
• Even in the formulation development of emulsions and suspension, projected diameter is important in that.
