Analysis Note

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 µm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.: Transmission electron microscopy (TEM) Scanning electron microscope Light microscopy Coulter^™ counter with MDF-systemCalibration of equipment is carried out with NIST-respectively BCR-particle size standards.

Application

Used to calibrate and monitor the performance of particle size analyzers.

Features and Benefits

suitable for routine instrument calibration checks, testing and corrections available in 5 mL and 10 mL pack sizes as neat samples

General description

Monodisperse polystyrene based micro particles (size: 200 µm) are a size standard, ideal for profiling particle size distribution (PSD) of a particle system.The particle diameter of 200 µm is characterized using Olympus optical microscope. The measuring instruments are calibrated using standards obtained from the Community Bureau of Reference (BCR, Belgium: Standards RM 165, 166 or 167) and from the NIST (SRM 1690, 1691 or 1692).
