Description

General description

Silicon dioxide based microparticles are ideal to obtain particle size distribution (PSD) profile of test samples.
The particle diameter of 4 μm is determined using Coulter Multisizer.

Application

Used to calibrate, qualify and check the performance of particle size analyzers, surface scanning instruments and particle counters.
Also used to prepare working fluid standard for use with a microfluidic particle concentrator.
