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.

  • For analysis of low molecular weight polymers in polar solvents
  • Specifically designed for polar samples
  • Mechanical stability for longer column lifetimes
  • Mixed bed technology delivers near linear calibrations for greater accuracy
