Optical particle size analyzer CPA 2-1

dynamic image analysisfor the pharmaceutical industryfor the food industry

Overview
The NEXOPART CPA 2-1 is a dynamic image analysis system for rapid and precise determination of particle size and particle shape of dry, non-agglomerating materials. It provides significantly higher sample throughput and additional measurement parameters compared with traditional sieve methods.

Benefits

• Fast results: typically within 2–3 minutes
• More detailed and numerous product data compared with sieve analysis
• Targeted evaluation using NEXOPART CpaServ software
• Wide set of parameters and immediate digital availability of measurement data
• Can also be used as a counting device
• 100% measurement of each individual particle

Applications / suitable materials
Optimized for dry, free-flowing, non-agglomerating bulk solids: fertilizers, blasting media, sand, coal, foodstuffs, pharmaceuticals, plastics, seeds, ceramics, glass, etc.

Principle and technology
The CPA 2-1 uses computer-based digital optical image processing: the sample is automatically dosed via a feed trough. Inside the measurement channel, an LED light line and a digital line-scan camera in backlighting produce high-resolution images. The line-scan principle prevents clipped images and particle loss; each particle receives an individual ID and measured values. With a GigE camera the system can also be operated from a notebook, increasing mobility and flexibility.

Peripherals & options

• Autosampler AS 6 or AS 12 for automated sample feeding (e.g., overnight operation)
• Dispersion unit for measurement of very fine materials
• NEXOPART CpaServ evaluation software for control, setup and analysis of the instruments

Comparison with sieve analysis
Traditional sieve analysis requires about 15–30 minutes per sample (including weighing, loading, analysis, cleaning); dynamic image analysis provides comparable or better information in typically 2–3 minutes.

Practical benefits
Suitable for incoming inspection, production control and process monitoring; reduces lab workload, noise and repetitive tasks while increasing sample throughput and reproducibility.
