Dispersion and Stability Analysis High Concentrated Dispersions and Packed Sediments X-rayed

Editor: Dr. Jörg Kempf

The separation analyser Lumireader X-Ray extends the proprietary near infrared Step-Technology after the inclusion of visible light now to X-radiation to characterize the separation behaviour of high concentrated, opaque suspensions and emulsions for a broad range of particle sizes under original conditions (no dilution required).

“This is a real ‘quantum leap’ into a new world — the X-ray technology“, explains Prof. Dr. Lerche, Managing Director of Lum. “The advantages of Lumireader X-Ray feature the direct and non-contact measurement of samples of highest concentration, the determination of concentration gradients in nano- and microdispersions and sediments and the determination of time and space-resolved mass concentration of dispersed phases based on separation phenomena. Even packing density gradients in sediments and filter cakes can be analysed.”

All dispersing agents are possible, being solvent or oil or water. Different measuring cells are available.

Lumireader X-Ray is the ideal extension to the established Lum instruments for dispersions. The identical measuring cells can optically be measured first in Lumisizer, Lumifuge or Lumireader PSA and then be analysed in Lumireader X-Ray. To the advantages of direct and accelerated stability analysis and particle characterization by near-infrared or visible light, the qualitative and quantitative determination of concentration profiles in separated and high concentrated phases is easily added.
