Size Determination of Latex Particles by Optical Methods

概要

論文の詳細を見る
Using plain turbidimetry and a method combining filtration and turbidimetry, determination of latex particle size was carried out on a series of samples. Plain turbidimetry is a convenient method for measuring the particle size of latexes, but it has one shortcoming. When original materials of latex particles in a sample series are not chemically identical, different calibrations must be achieved because the refractive index is not the same among the original materials. The combined method turned out to be more versatile than plain turbidimetry, due to insensitivity to changes of the chemical properties of the particles. Sensitiveness was restricted to only the particle dimension.
