Effect of Particle Size on Oligomer Separation Using

Effect of Particle Size on Oligomer Separation Using Agilent PLgel and GPC/SEC Technical Overview Introduction As predicted by the Van Deemter equation, as the particle size of a column is decreased, so the resolution improves. The operating pressure will increase as the particle size of the packing is reduced. This effect is demonstrated using

Particle Size Distribution Functions

The most common particle size distribution is called the log-normal distribution which is based on the Gaussian distribution. A log-normal distribution is natural to a system where particles are formed or broken up in accordance with some power of particle size such as the volume or surface area.

Determining Bulk Powder Particle Size through Texture

Particle size analysis is routinely employed for material quantification in a growing number of fields (e.g. pharmaceutical, food, metallurgy). The term "particle size" is not an unambiguous one. Problems can arise if the particles have a very large aspect ratio, such as fibers or needles, leading to disagreements between different particle size analyzers [1]. For this reason, we consider
