Description
Electron microscopes, whether scanning (SEM) or transmission (TEM), are techniques for microscopic observation of particles at very high magnifications, even exceeding one million times. Through these microscopes, you can observe the morphology and size of particles. Using TEM, you can also view the interior of particles. One of the most common analyses for these images is plotting a histogram. In these graphs, the particle size distribution is also displayed.
Particle Size Histogram Analysis
A histogram is a fundamental tool for analyzing particle size from electron microscopy images. It provides a clear and comprehensive view of how particles are distributed within a sample.
What a Histogram Shows
-
Distribution of particle sizes across defined ranges (bins).
-
Frequency of each size range, showing which particle sizes are most common.
-
Overall trends, such as narrow vs. broad size distribution.
Why It’s Important
-
Helps identify uniformity of particles (important for consistent material properties).
-
Reveals agglomeration or clustering of nanoparticles.
-
Provides quantitative data beyond simple average particle size.
-
Essential for comparing samples processed under different conditions.
Applications in Research & Industry
-
Nanomaterials development and quality control.
-
Powder metallurgy and composite materials.
-
Coatings and thin films characterization.
-
Corrosion, mechanical, and functional property evaluations.
With histogram analysis, you gain a complete picture of particle size distribution, enabling data-driven decisions in both research and industrial applications.
