Beschreibung

Allgemeine Beschreibung

Glaswollstopfen werden oft für GC-Inlet-Liner genutzt, um die Probenverdampfung zu verbessern und/oder um zu verhindern, dass nicht flüchtiges Material in die Säule gelangt. Sie können auch in gepackten GC-Säulen, Lösungsmitteldesorptionsröhrchen sowie Thermodesorptionsröhrchen und für die Purge-Trap-Technik zum Zurückhalten des adsorbierenden Materials eingesetzt werden.

Glass wool is made up of short glass fibres and is nonflammable in nature. It is widely considered as a thermal insulation material in ships, automobiles, air conditioning ducts and water supply pipes. Furthermore, it is also suitable as noise absorbing material in concert halls, studios and movie theatres. Above all that it is non carcinogenic to humans.[1] Glass wool treated with phosphoric acid is highly advantageous as it prevents usage of more amount of glass wool for metal column tubing.[2] Moreover phosphoric acid is the most effective acid additive which is generally required in the stationary phase of the chromatographic column for deactivation of both the support and metal column tubing that is the glass wool.[3] Glass wool treated with phosphoric acid is highly suitable for the analysis of free fatty acids (FFA).[2]

Anwendung

Glass wool column maybe used for the separation of lymphocytes in human blood.[4]
