Opis

General description

Silicon dioxide based microparticles are suitable for profiling particle size distribution (PSD) of test samples.
The particle diameter of 2 μm is evaluated using Coulter Multisizer.

Application

Used to qualify and monitor the performance of particle size equipment.
Also used as a calibration standard to:

• assess 3D particle tracking ability of optical diffraction tomography instrument for optically trapped silica beads
• synthesize inverse patchy colloids (IPCs) for phase-behavior studies of heterogeneously charged particles

Features and Benefits

• suitable for routine instrument calibration monitoring, testing and corrections
• particle size traceable to Community Bureau of Reference (BCR) standards
• available in 5 mL and 10 mL pack size as neat samples
