→Application-based selection
The measurement range is defined by the application.
We first evaluate the process medium, measurement objective, and operating conditions. We then select the appropriate instrument and configuration.
What is present in the process?
Particles, droplets, bubbles, crystals, cells, or combinations of dispersed phases.
Under what conditions does it operate?
Concentration, pressure, temperature, flow velocity, viscosity, and fouling tendency.
What decision will the data support?
Process development, endpoint detection, quality control, or closed-loop process control.
Which configuration is appropriate?
Probe, illumination, accessory, process connection, and analysis algorithm.
Nominal portfolio rangeSOPAT: 0.5 µm–50 mmParsum: 20 µm–6 mmThe effective measurement range depends on the configuration and sample matrix.

Identify and classify each individual object
Automated image analysis recognizes individual objects and, depending on the application, can distinguish particles, droplets, bubbles, crystals, and aggregates using optical and morphological features.
What can be monitored continuously
Particle-size distribution
Histograms, cumulative distributions, percentiles, and shifts in the particle-size profile.
Particle counting
Number of detected objects and evolution of the analyzed population throughout the process.
Class differentiation
Distinguish particles, droplets, bubbles, crystals, cells, or aggregates when the application allows.
Shape and morphology
Feret diameters, circularity, elongation, and other morphological characteristics.
Real-time trends
Monitor growth, breakage, agglomeration, crystallization, and process stabilization.
Operational decisions
Compare batches, evaluate operating adjustments, and support quality-control decisions.
All charts and images in this section were extracted from the official SOPAT corporate presentation. Available variables and class differentiation depend on instrument configuration, sample matrix, and application validation.
