Colloidal silicas are typically aqueous suspensions in the range of 30 – 500 nm in diameter. Most size measurements of colloidal silica are performed using dynamic light scattering (DLS) instruments such as the SZ-100 Nanoparticle Analyzer. The LA-960 Laser Diffraction Analyzer can uniquely measure down to the 30 nm size range, so this laser diffraction instrument is also …
