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.

Characterization of suspensions and emulsions by means of multiwavelength reflectance and machine learning methods

2022, English

Monitoring of product compositions is essential for the control of unit processes. Product quality parameters have to be observed in almost real-time and the sensor should be used for different applications. This contribution introduces the Multi-Reflectance-Spectroscopy (MRS) as an innovative technique based on multiwavelength reflectometry for in-situ quality/process control of suspensions and emulsions.

Filter Media And Membrane Testing By Micro- And Nano-particles: Determination Of Size And Count By A Single Particle Spectrophotometer

2022, English

Filter media design and its performance in the production process demand a thoroughly quantitative assessment. Important characteristics are filter types, used materials, permeability, resistance, to name a few. In this paper we describe a recently developed flowcytometer (LUMiSpoc®).

Sedimentation of Bidisperse Polymer Suspensions in Aqueous Polymer Solutions

2022, English

Dissolved NaCMC induced flocculation affecting sedimentation even for micron-sized model particles if viscous forces are sufficiently high. At high NaCMC concentrations shear-thinning like separation behaviour was observed, and in case of the smaller polymer particles also a lack of traceable separation below a critical centrifugal force.
