Particle size determination using turbidimetry. Capabilities, limitations and evaluation for on-line applications

There are numerous reports of the use of turbidimetry for the determination of either the particle size or the particle size distribution (PSD) for a variety of latex systems. There has been a controversy in the literature, on whether turbidimetric techniques are at all capable of providing a valid estimate of the particle size distribution of a suspension. When attempting to estimate the PSD in poly(vinyl acetate) latexes in our laboratories …
