Colloid emulsions in their native environment require particle size determination in high concentration since there are concerns about changes in sample morphology upon dilution eg break up of aggregates. For proteins and other samples with very low concentration and for weakly scattering ...
"Triple Detection" in Gel Permeation Chromatography
11-11-2005
Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole ...
