Recycling Tetrahydrofuran (THF)

Tetrahydrofuran is used to dissolve polymers for molecular weight analysis by GPC (Gel Permeation Chromatography).

Average molecular weight is an important property of polymers and is an indication of strength and flexibility.

After use, the waste THF is contaminated with:

  • Polymer fragments
  • Monomers
  • Other solvents
