The NEXOPART CPA 2-1 is a dynamic image analyzer for laboratory particle-size and particle-shape analysis of dry, free-flowing, non-agglomerating bulk materials. Samples enter the measuring channel through the feeder, where an LED light source and digital line-scan camera capture images in backlight mode for real-time processing with CpaServ. Labsun is the exclusive distributor for NEXOPART products in China.
Dynamic image analysis principle
The system uses computer-assisted digital optical image processing. The scanning principle is designed to reduce cropped or missed particle images and generate high-resolution data for individual particles. It provides particle-size distribution and particle-shape information and can also be used for counting.
Key features
Digital measurement with real-time result processing.
CpaServ software for control, settings and evaluation.
GigE Vision connectivity for flexible system placement.
Compact, mobile configuration for rapid repeat measurements.
Automatic funnel cleaning and height adjustment.
LED backlight imaging.

Method setup and digital workflow
After defining the parameters for a material, subsequent analyses can be started and completed digitally with one operation.
CpaServ controls the instrument, configures analysis parameters and evaluates particle-size, shape and counting results in real time.
Line scanning assigns an individual ID to each particle and avoids cropped particle images for complete particle acquisition.
AS 6 or AS 12 autosamplers are separately available for multiple samples; assess the need for a dispersing unit for fine materials.
Particles leave the feed chute and enter the LED backlit measuring channel for line-scan imaging.
Samples and applications
Example materials include fertilisers, blasting abrasives, sand, coal, food, pharmaceutical materials, plastics, seeds, ceramics and glass. Confirm sample condition, target range, shape requirements and sample preparation before selection.
Optional peripherals
An AS autosampler can handle prepared samples sequentially, while an ultrasonic dispersion unit may be evaluated for finer or agglomerating material.
Sieving evaluates mass fractions passing apertures; dynamic image analysis also evaluates size and shape. Define the result before choosing dry/wet operation and automation.
