Benefits of the Dynamic Image Analysis Method

Using dynamic image analysis, it is possible to capture an image of particles, identify the particles within the image, and measure their size and shape. Each step of the process is simple and easy to understand.

Because dynamic image analysis provides a direct view of particles, it is possible to analyze their shape and size effectively.

Once the image analysis method confirms the size and shape of every individual particle present in the image, these can be summed up to form a statistic that provides accurate details of particle size or shape distribution.

Dynamic image analysis provides several other advantages.

• Efficiency: Higher measurement efficiency is ensured by the continuous particle flow passing through the measurement zone.
• Oversized Particle Sensitivity: Dynamic image analysis makes estimating the size of oversized particles possible.
• Reliable Results: Statistical significance of measurement results is ensured by maximizing the number of measured particles.

BeVision D2 Hardware: Guaranteed Accuracy and Efficiency

The BeVision D2 features a comprehensive range of hardware, allowing it to measure the size and shape of particles across a wide range of applications.

Selecting the most appropriate hardware for the sample’s material properties can help measure particle size and shape with optimal efficiency and accuracy.

Shape Parameters

• Size difference in two directions; for example, L/W ratio, aspect ratio, and ellipse ratio
• Round-likeness and rectangle-likeness, for example, irregularity, compactness, circularity, extent, and box ratio
• Contour concavity; for example, concavity, convexity, and solidity
• Elongated particle measurements, for example, elongation and straightness
