Agilent PolarGel-L (Low Molecular Weights)
The PolarGel range is ideal for use with polar solvents, for example
dimethyl formamide and dimethyl sulfoxide, and for solvent combinations
such as tetrahydrofuran with water. These eluents are very useful in
GPC/SEC to separate polar materials, such as polar resins, modified
polysaccharides or complex polar polymers that are difficult to analyze in
traditional SEC solvents, such as tetrahydrofuran alone. PolarGel-L is used
for low molecular weight polar polymers and PolarGel-M for high MW
polar polymers.
With polar polymers, highly polar groups can lead to non-specific
interactions and secondary separation mechanisms when using polar
solvents and traditional non-polar styrene/divinylbenzene columns.
Additives and/or column conditioning are normally required to reduce
these interactions. PolarGel has no need for these interventions, and also
avoids the interactions and secondary effects that produce chromatogram
distortions.
