- Demixing analysis - including particle size analysis
 |
Historic dispersion stability analysis: differences over time in multiphase samples were judged by the eye, measured with rulers, clock and calendar. It took much time and was not precise. These times are over now ! |
 |
Demixing phenomena like sedimentation, flotation and coalescence are measured directly and simultaneously over the whole sample length with the innovative and patented STEP technology with LUMiReader, LUMiFuge and LUMiSizer. LUMiCheck allows a simple and fast stability ranking measured from the bottom of the cuvettes.
Application: monitoring of product quality during the production process - rapid improvement of formulations - study of factors controlling coalescence and aggregation - acceleration of common aging tests - additional: optimization of separation processes - dewatering of sludge, removal of suspended solids - separation of products, additives and catalysts - cracking of emulsions (e.g. crude oil) - selection of flocculants, demulsifiers and their dosing
Application industries: bitumen, petroleum, crude oil, tar - colors, pigments and inks: paints, automobile, printing- and other inks, pigment dispersions - ceramic materials - cutting emulsions - food: baby- and infant nutrition, dressings and sauces, functional food, drings, ketchup, milk products - pharmaceutical and cosmetics: liquid formulations, cremes, shampoos, toothpaste

What is LUMiCheck: LUMiCheck measures the change of near infrared backscatter at the bottom of up to 8 vials simultaneously. For a simple and fast stability ranking with different demixing phenomena. Standalone unit with SD card for data storage and transfer. |
What is LUMiReader: LUMiReader is a demixing photo reader, microprocessor controlled, for objective and traceable classification of stabilisation and separation mechanisms in dispersions and foams at gravity. It records simultaneously over the whole sample heights the kinetics of transmission changes for several samples with much greater sensitivy than by naked eye. An innovative principle enhances the separation velocities up to 10 times without mechanical stress. SEPView, a windows based software, displays in real time the evolution of any demixing phenomena and quantifies sedimentation, flotation, aggregation, flocculation, coalescense and cristallization for each individual sample. |
What is LUMiFuge: The LUMiFuge is a microprocessor controlled, analytical photo centrifuge for rapid and traceable classification of stability and separation of even concentrated dispersions. It records the kinetics of transmission changes for 8 samples simultaneously, like a time lapse motion picture, at up to 2300 times earth gravity and higher space resolution than by naked eye. LUMiFuge has integrated temperature control from 4-60°C. SEPView, a databased software displays in real time the evolution of a large variety of demixing phenomena and qualifies sedimentation, flotation, aggregation, flocculation, polydispersity and shelf life for each individual sample. |
What is LUMiSizer: The LUMiSizer uses the principle of Centrifugal Separation Analysis to measure particle size, demixing and consolidation in one instrument. The "complete dispersion laboratory" analyses up to 12 samples at once. It combines a high end, PC-controlled centrifuge with a patented unique optics system (NIR-light source and a linear high resolution detector) to monitor the concentration profile over the entire length of a sample while it is being subjected to centrifugation. The Software is based on a comprehensive database solution. The analyser accelerates at variable speeds the demixing, allowing rapid stability testing and consolidation studies in highly concentrated dispersions in minutes and hours instead of days or weeks. It can also perform high-resolution particle size analysis in the range of 100 nanometer to 300 micrometer |
