Dynamic image analysis: fully automated determination of particle size and shape of your sample with the NEXOPART CPA 2-1
Dynamic image analysis (DIA) has established itself as a key technology in modern particle analysis. This method is becoming increasingly important, particularly in the chemical industry and engineering – wherever precise information about particle size, shape and distribution is essential for quality assurance and process optimization. In the field of dynamic image analysis, NEXOPART offers the CPA 2-1 for use in the laboratory and the CPA 2-1 ONLINE for use in ongoing production processes.
Application examples - Industries with high demands on dynamic image analysis
Dynamic Image Analysis (DIA) is specially designed for dry, free-flowing and non-agglomerating bulk materials such as fertilizers, abrasives, sand, coal, food, pharmaceuticals, plastics, seeds, ceramics or glass. Precise particle characterization is of great importance in numerous industrial sectors, including:
Feed industry: Control of feed types and qualities. A specific grain size distribution is important for good feed intake; customers want individual mixtures and no damage to the feed flakes
Chemical industry: Shape analysis for detecting defective products in the manufacture of, for example, catalysts, plastic granulates, etc.
Blasting abrasive industry: Shape measurement, measurement of material wear, e.g., steel or plastic balls.
Wood industry: Length and width are important process parameters for granulates and pellets, for example.
Fertilizer industry: To obtain information about ingredient separation and moisture retention.
Food industry: Influence on solubility, e.g., of sugar or salt.

What is dynamic image analysis?
L
Dynamic image analysis is an optical method for automated particle measurement in which particle samples are captured and analyzed in free fall. Using a high-speed camera, each individual particle is recorded and analyzed in real time for shape and size—with an accuracy that often surpasses traditional methods such as sieve analysis or laser diffraction. The result: the meaningful data obtained is indispensable for process control and product development.

NEXOPART CPAServ software with alignment intelligence: intelligent, highly flexible alignment built into the CpaServ software. Thanks to the intelligent alignment, measurement data on particle size distribution can be adapted to any other measurement method. Comparison data pairs from concrete results serve as the basis. Due to the required approach, no generalization takes place. All data is precisely adapted to the requirements and conditions of the respective application. NEXOPART A.I. is suitable for regular particle size distribution representations and particle size distribution-specific applications.
Advantages of dynamic image analysis in particle analysis
High accuracy and reproducibility: Thousands of particles are captured in a short period of time, resulting in precise and reliable measurements.
Real-time analysis: Dynamic image analysis provides immediate feedback, allowing for quick adjustments in the production process.
Comprehensive shape and size measurement: In addition to particle size, complex shape parameters such as circularity, length-to-width ratio, equivalent diameter and surface roughness can also be recorded.
Automation and process integration: Modern systems can be seamlessly integrated into existing production lines and automate quality control.
Application in the chemical and pharmaceutical industries:
L
For professionals in the chemical and pharmaceutical industries, dynamic image analysis is an indispensable tool for ensuring product quality. Whether in powder production, granulation or suspensions, precise particle characterization helps to identify and correct process deviations at an early stage. This minimizes waste, increases product safety, and supports compliance with regulatory requirements.
Optimization of analysis processes through dynamic image analysis:

FAQ about particle size and shape analysis
What is the difference between static and dynamic image analysis?
L
Static image analysis captures stationary particles on a carrier and provides high-resolution, detailed images, but is only suitable for a small number of particles and is time-consuming. It is mainly used for detailed laboratory analyses. Dynamic image analysis captures moving particles in a measuring cell using high-speed cameras. It enables fast, automated measurements of large quantities of particles in real time and is suitable for inline process control, but has limitations with very small or transparent particles.
What are the advantages of dynamic image analysis—is it a replacement for traditional sieve analysis?
L
1. Speed: Real-time measurement without manual evaluation
2. Precision: High resolution and detailed shape analysis
3. Wide measuring range: From a few micrometers to several millimeters
4. Reproducibility: Consistent results with repeated measurements
Is NEXOPART's dynamic image analysis suitable for inline process control?
L
Yes, NEXOPART's ONLINE and INLINE systems are specially designed for integration into production lines and enable continuous monitoring of particle properties – ideal for real-time quality assurance. The NEXOPART CPA 2-1 ONLINE can be integrated into production processes in a variety of ways. It is particularly suitable for incoming inspection, production control and process monitoring in particle size and particle shape analysis. The INLINE enables 24/7 real-time monitoring of bulk material at the loading station or on the conveyor belt.
Which norms and standards are met?
L
Modern systems for dynamic image analysis meet international standards such as ISO 13322-2 for image analysis methods for particle size determination. The CPA 2-1 analyzer from NEXOPART meets countless standards. The most important ones are: ISO 9276-1 to -6, ISO 13322-2, EU Machinery Directive 2006/42/EC (from CE declaration), DIN EN IEC 61010-1 (from CE declaration), and ASTM E2651.
How complex are maintenance and calibration?
L
The systems are generally low-maintenance and have automatic calibration functions. However, regular cleaning of the optics and checking of the light source is recommended.
What is the Feret diameter?
L
The Feret diameter is the distance between two parallel lines that touch an object (e.g., a particle) and is used in dynamic image analysis for shape classification, e.g., to distinguish between needle-shaped, platelet-shaped or spherical particles. The value is particularly useful for non-spherical particles, as it better describes the actual extent than the circle diameter.
