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.
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[1]
- as a test standard to validate denoising method used in optical diffraction tomography[2]
- in accelerated annealing experiments involving colloidal silica monolayers[3]
- to evaluate the measurement accuracy of color-coded LED microscopy (cLEDscope) technique[4]
- as a calibration standard in optical trapping system to measure surface mechanical properties[5]
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

Are these Silica particles partly porous? What is the approximate refractive index?
1 answer-
These beads are considered to be non-porous. BET experiments with comparable particles revealed practically no inner surface. As mentioned in the PROPERTIES section, the particle size is 5 μm with a standard deviation of ≤0.35 μm.
