Random thoughts, science, applications, ideas
The idea behind this notes section is to show examples of what kind of results you can expect using the LUMiseries of emulsion and dispersion analyzers. It consists of paper reviews and non-published data and results.
The aim is not to proclaim we are the best. I believe a successful lab has many tools.
The hope is to promote some thoughts and ideas on how our technologies may benefit your workflow.
Is it marketing? Probably. But the accurate and 100 percent reproducible.

Everything below is my thoughts, data, and comments. The order, frequency, and posting date have no rhyme or reason. Thank you for your time and interest.
Rapid assessment of sedimentation stability in dispersions using near-infrared transmission measurements during centrifugation and oscillatory rheology
Abstract: The LUMiFuge analyzer was used to investigate the sedimentation kinetics of bentonite/xanthan gum mixtures and compare them to results obtained using rotational and oscillatory rheology.
Particle size distribution by space or time-dependent extinction profiles obtained by analytical centrifugation concentrated systems
Abstract: The particle size distributions of dispersions of fine particles were determined by an analytical photocentrifuge, which allows for measuring space and time-resolved extinction profiles (STEP™-Technology) during the centrifugation of up to 12 samples simultaneously. This type of centrifuge provides a powerful tool for characterizing and quality control of dispersions. Measurements of dispersions, with monomodal, multimodal, and broad particle size distributions in the nanometer and micrometer range are presented. Also, analytical centrifugation has a great potential to measure dispersions without dilution. Therefore, two effects will be discussed, hindered settling and multiple scattering. Experimental results from concentrated suspensions and emulsions show the applicability of this new measurement principle. Results will be compared with other measurement techniques (SEM, PCS, Laser diffraction).
