Certified Nanosized Particle Size Standards

To calibrate or to validate the different properties of all particle sizing instruments BS-Partikel GmbH enlarged there product series of high concentrated particle size standards (HS Series) by six nanosized standards. All of them having spherical shape and a mean particle diameter between 180 nm and 725 nm and will be shipped in dropper-tipped bottles of 20 ml with a certificate which also shows the measured particle size distributions as graphical figures. The figure besides displays a measurement of a mixture of all these six size standards. This had been measured with a high resolution analytical disc centrifuge as the most precise method for diameter determinations available on the market at present.
