Beschreibung

Allgemeine Beschreibung

Tetrahydrofuran(THF) is commonly used as a solvent in liquid chromatography. THF is widelyutilized as a solvent in non-aqueous size-exclusion chromatography (SEC),because it is a good solvent for various polymer types.

Anwendung

Tetrahydrofuran can be used as a mobile-phase component in the:

• Analysis of tocopherols.
• HPLC analysis of self-associated cationicpolymer (NREP).
