Effect of Injection Volume on Oligomer Separation with Agilent PLgel and GPC

Particle Size and Injection Volume Affects Resolution of Agilent PLgel 100Å Columns Technical Overview Introduction Two factors that can affect the efficiency and therefore resolution of columns for gel permeation chromatography/size exclusion chromatography (GPC/SEC) are the particle size of the…

Effect of Flow Rate on Oligomer Separation Using Agilent PLgel and GPC/SEC Technical Overview Introduction In gel permeation chromatography, the resolution of oligomers improves as flow rate is reduced. However, the run time is obviously increased as a result. This…

Calibrating Agilent PLgel 3 µm 100Å Columns with Polystyrene Standards for GPC Technical Overview Introduction Agilent PLgel 3 µm 100Å columns are designed specifically for the analysis of low molecular weight discrete molecules in organic solvents. Molecular weight information of…

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…
