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 and shape 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., abrasives, plastics or grinding media.
Wood industry: Length and width are important process parameters for granulates and pellets, for example.
Fertilizer industry: To obtain information about transport, dosage, application behavior, and solubility.
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 size and shape — with an accuracy that often surpasses traditional methods such as sieve analysis. The result: the meaningful data obtained is indispensable for process control and product development.
What is NEXOPART A.I.?
L
NEXOPART CPAServ software with alignment intelligence: intelligent, highly flexible correlation built into the CpaServ software. Thanks to the intelligent correlation, measurement data on particle size distribution can be adapted to any other measurement method. Due to the required approach, no generalization takes place. All data is precisely adapted to the requirements and conditions of the respective application.
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 and equivalent diameter 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 industries:
L
For professionals in the chemical industries, dynamic image analysis is an indispensable tool for ensuring product quality. The 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:
L
Engineers and quality managers benefit from dynamic image analysis through optimized analysis processes that enable faster decision-making. The combination of image processing and statistical evaluation provides detailed insights into particle structure, supporting the development of new products and the improvement of existing processes.
Dynamic image analysis with NEXOPART is more than just a measurement method – it is a strategic tool for increasing your product quality, reducing errors, and optimizing industrial processes. For companies that rely on the highest product quality and maximum safety, it is an indispensable part of modern analytics.

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 by using a high-speed camera. It enables fast, automated measurements of large quantities of particles in real time and is suitable for 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 micrometers to millimeters
4. Reproducibility: Consistent results with repeated measurements
Is NEXOPART's dynamic image analysis suitable for process control?
L
Yes, NEXOPART's ONLINE system and INLINE trend analysis 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 brings laboratory-standard measurement technology to production and can be integrated into production processes in a variety of ways. It is particularly suitable for production control and process monitoring in particle size and particle shape analysis. The INLINE enables 24/7 real-time monitoring of bulk material on the conveyor belt or at the loading station.
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 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 and ASTM E2651.
How complex are maintenance and calibration?
L
The systems are generally low-maintenance. However, regular cleaning of the optics and checking of the light source is recommended. The CPA 2-1 ONLINE features integrated pneumatic cleaning of the optics and light source.
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 size classification.
