We developed the Partica CENTRIFUGE CN-300, centrifugal nanoparticle analyzer to measure the size distribution of nanoparticles by using the photo-centrifuge method of the sedimentation technique. We validated this apparatus by accurately measuring several kinds of sample distributions such as mono-dispersed, poly-dispersed, or broad distributions. We confirmed high performance for accuracy, resolution and repeatability in the apparatus by the use of certified reference standards. Therefore, The Partica CENTRIFUGE can be used as an evaluation tool for nanomaterials being developed and commercialized in the nanomaterial field.
