A study published online on April 25, 2019 in Applied Nanoscience explored the potential toxicity of raw manufactured nanomaterials (MNMs) in paints using titanium dioxide and carbon black. The study, Characterization of water-based paints containing titanium dioxide or carbon black as manufactured nanomaterials before and after atomization, sought to characterize particles at each stage of the production and use of paints containing these nanoparticles: “raw MNMs, suspensions of MNMs, paint containing them and paint aerosol produced.” According to the results of this research, “This behavior indicates that minor or no potential toxicity exerted by MNMs in this type of complex products may be observed.”
In the process of characterizing these particles, the researchers relied on the CPS Disc Centrifuge 24,000 operating at 22,000 RPM. The disc centrifuge is able to provide analyses in as little as one-third the time of other instruments.
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.
