Particle size and shape parameters can be accurately acquired through dynamic image analysis (DIA), which offers a viable approach for extensively studying particle size and shape. In contrast to static image analysis (SIA), DIA continuously captures images of particles in motion and subsequently analyzes them to determine particle size and shape parameters. This method encompasses the measurement of both suspended and free-falling particles, as well as those prone to agglomeration.
Static image analysis produces high-quality images of a limited number of particles, while dynamic image analysis is capable of analyzing numerous particles in a brief period of time. Consequently, dynamic image analysis is primarily suitable for the size and shape analysis of larger particles, and it possesses the following characteristics:
1. Easier operation and lower susceptibility to human errors
2. Enhanced sensitivity to larger particles
3. Swift and effective data analysis
4. Increased capacity for handling samples
5. Results that are highly representative and precise
Method of Measurement
Determining the size and shape of particles using DIA involves four steps:
1. Capturing images
Special digital cameras are used to take images that magnify particles while preventing motion blur. This is often done in combination with a microscope. The particles are in motion, and it's possible to deagglomerate particles in both dry and wet modes.
2. Processing images and identifying particles
Appropriate software processing improves the images by eliminating isolated pixels and outlining particles, adjusting variations in brightness and signal noise, and separating agglomerated particles.
3. Calculating size and shape parameters of particles
The software calculates the size and shape parameters of each individual particle.
4. Analyzing statistics and classifying data
Particles are classified based on their size and shape parameters.
