The journal Physics of Wave Phenomena published a study in April that used the CPS Disc Centrifuge to measure selenium nanoparticles. The study, „Laser Fabrication and Fragmentation of Selenium Nanoparticles in Aqueous Media“ investigated using laser ablation to form selenium nanoparticles. 

According to the study, selenium is used to prevent diseases, such as arthritis, cardiovascular disease, muscular dystrophy, and more. It is used as a food additive and is a detoxifying agent which counteracts heavy metals. According to the paper, selenium nanoparticles show promise, because they have „high activity, low cost, biocompatibility, and low toxicity.“ To fabricate the nanoparticles, the researchers used laser ablation on polycrystalline selenium in pure water.

The CPS Disc Centrifuge was used to determine mass and size distribution functions of the selenium nanoparticles.

Around the world, researchers rely on CPS Instruments when accuracy matters most. The CPS disc centrifuge provides a higher resolution than light scattering or particle counting methods at a much faster rate of analysis than competitive sedimentation-based particle sizing instruments. Whether replacing an aging system or increasing capacity with a new system, an investment in a CPS disc centrifuge is an investment in consumer confidence.
