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.

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...
Characterization of DNA-polymer complexes – Application of LUMiSpoc® for analyzing reaction dynamics and kinetics
2024, English
The time-dependent DNA-polymer complexation, with potential applications in gene therapy, was characterized using the LUMiSpoc®. In this study, the influence of different polymer concentrations and mixing methods on the complexation kinetics and dynamics was analyzed. The measurement method enables a real-time analysis of the complexation process by recording the number-based particle size distribution and concentration.
The results showed a time-dependent increase of the median x0,50 from initially <250 nm to about 600 nm...
Characterization of raw materials and semi-finished products for battery industry
2024, English
In the webinar you learn more about how LUM instruments can help you to determine the particle size distribution of raw materials for batteries and fuel cells, characterize dispersibility and separation of battery pastes in original concentration and determine the adhesive and coating strengths of layers in electrodes.
