Methods For Determining Particle Size

September 20, 2025 by Anshu Kumari

Methods For Determining Particle Size explain techniques like microscopy, sieving, and sedimentation.
Methods For Determining Particle Size help in quality control of pharmaceuticals, food, and materials.
Particle size can be measured using different principles and instruments.
These methods can be broadly classified as:

Category	Examples of Techniques
Counting Methods	Optical microscopy, electron microscopy
Separation Methods	Sieving, sedimentation
Spectroscopic Methods	Laser diffraction, dynamic light scattering
Electrical Methods	Coulter counter
Surface Area-Based Methods	Adsorption techniques (e.g., BET method)
