Particle Characterization

The optical process of Dynamic Image Analysis (DIA) provides results for a wide measuring range, delivers multiple shape parameters and evaluation possibilities for particle size. Dynamic Image Analysis (DIA) uses a high-end camera and LED light source to capture images of particles as they free flow in front of the camera lens and LED. In the event that particles have an tendency to agglomerate or are not free flowing the particles can be suspended in solution and circulated through a wet dispersion module. This is an ideal technique for all applications that require accurate and reproducible measuring results for both particle shape and size distribution of powders and bulk solids as well as of suspensions and emulsions.

Then using powerful software algorithms, a computer will calculate measurements that provide size information for different length and width models, diameters and perimeters. In addition to providing information that describes the particle shapes such as sphericity, aspect ratio, and convexity. Images of the particles can also be viewed in the Particle Gallery to provide additional analysis and insight into the size and morphology of the particles.

Compared to traditional sieve methods, Dynamic Image Analysis (DIA) offers a number of valuable process improvements. DIA is consistently stable between measurements and over time, removing risk of individual operator bias, manual calculations, and sieving result inaccuracy (or curve shift) based on degradation and misalignment of sieve screen openings. Dynamic Image Analysis saves considerable time over sieving, while reducing or eliminating costly errors, especially in high throughput processes or when working with staff resource constraints. Limitations on resolution are directly related to the number of sieve pans that can be stacked on a manual sieve shaker. DIA offers endless numbers of channels for significantly expanded particle size distribution data, with a much broader sample volume that is representative of your material.
The conversion from sieving related to size distribution, and microscopy (SIA) for morphology, analysis allows for enhancements in regulatory compliance and offers a number of improvements to benefit your business and staff. Dynamic Image Analysis (DIA) is an excellent replacement for sieving as it provides for faster and reproducible results.
