Advantages and Disadvantages of Optical Microscopy in Particle Sizing

Here is mention some advantages and disadvantages of optical microscopy in particle size analysis let’s check it.
Advantages of Optical microscopy in Particle Sizing:

• It is the simplest method for particle size analysis.

• The shape analysis is available by Optical microscopy method.

• It allows viewing the particles.

• Contamination and agglomeration of the particles can be detected.

• Simple to count the particles.

• An electron microscope or scanning electron microscope can be used to measure very small particle size.

Disadvantages Optical microscopy in Particle Sizing:

• Optical microscopy takes a long test cycle.

• It is not possible to test the ultrafine particles by the microscopy method.

• The depths of the particle are not accessible.

• Testing of ultrafine particles not possible.

• This is a tedious and slow method.
