Particle size standards may be used to validate sizing instruments across their dynamic ranges. They are suitable for use in the performance of routine instrument calibration checks and corrections, and in the support of practice standards, such as those published by ISO, ASTM International, CEN and other organizations. Additionally, the use of reference material permits the standardization of results between runs, instruments, laboratories and over time.
Polysciences, Inc. is a global leader in the manufacture of NIST traceable particle standards for Quality Control, Calibration and Sizing. Our Precision Particle Size Standards are widely used for clean room certification, filter testing, and wafer scanner calibration equipment.
Our NIST Traceable Particle Size Standards are monodisperse polystyrene spheres available in diameters ranging from 40nm-175µm. Suspensions are conveniently packaged in dropper bottles at 1% solids, and each bottle is provided with a Certificate of Traceability.
