Descripción

General description

Silicon dioxide based microparticles are ideal to determine particle size distribution (PSD) profile of test samples.
The particle diameter of 5 μm is measured using Coulter Multisizer.

Application

Used for regular calibration and checking of particle size instruments. Also used:

• to study transport properties of microscopic particles via heterogeneous media
• as a test standard to validate denoising method used in optical diffraction tomography
• in accelerated annealing experiments involving colloidal silica monolayers
• to evaluate the measurement accuracy of color-coded LED microscopy (cLEDscope) technique
• as a calibration standard in optical trapping system to measure surface mechanical properties

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 pack size as a neat sample
