Dispersion Letters - Aims and Scope
Dispersion letters is an information platform dedicated to spread and exchange information between those working in various fields of dispersion research, phase separation, formulation, dispersion processing and quality control.
It is dedicated predominantly to experimental and applicational work explored with analytical instruments developed by LUM. Dispersion Letters publishes on-line articles, technical notes and reviews.

Gravitational Separation Monitoring by X-ray based STEP-Technology® (LUMiReader® X-Ray): Measuring Principle and Validation
2025, English
The new LUMiReader® X-Ray introduces a powerful measurement principle built on quasi-monochromatic X-ray radiation, enabling precise analysis of even highly concentrated, opaque, or transparent nanoparticle suspensions. With minimal sample volumes, disposable cells that eliminate dilution, and simultaneous spatially resolved measurements, it delivers unmatched efficiency and accuracy. Advanced features include direct monitoring of sedimentation and emulsions, high-resolution particle size and mass fraction determination, and fully integrated data evaluation in SEPView® 7. Designed for reproducibility and precision, it sets a new standard in separation monitoring technology.
Monitoring of Critical Raw Material Recycling from Battery Black Mass using the LUMiReader® X-ray and LUMiSizer®
2025, English
With demand for clean energy soaring, the race to reclaim critical materials from spent batteries is on.
But how do you separate value from toxicity in complex black mass?
Discover how the LUMiSizer® and LUMiReader® X-Ray are transforming battery recycling - and what their findings could mean for the future of sustainable energy.
Real-time testing & consolidation fingerprinting using X-radiation extend knowledge in formulation, processing & QC
2025, English
On March 12, 2025, Anamet S.R.O. invited Dr. Arnold Uhl via Webex to give a talk during a hybrid event taking place in Brno University.
In the 28 minute webinar you will get to know various case studies in which light or laser-based technologies would be at a loss.
Only thanks to X-rays was it possible to gain insights into consolidation and real-time stability, which makes the work of formulators, process technicians and quality control officers much easier.
Characterization of PMMA particles in the nanometer to sub-micron range - Application of the LUMiSpoc®
2025, English
The LUMiSpoc® is presented as a powerful characterization tool for monomodal nanometer- to micron-sized PMMA particle dispersions with median nominal particle sizes of 105 nm, 125 nm and 161 nm.
Using Single Particle Light Scattering (SPLS®) technology, the number-based particle size distribution and number concentration were precisely determined and analyzed according to Mie theory even for the complicated scenario in which the three monomodal particles were mixed together creating a trimodal system...
