Merck, 20383, Glass Wool

General description
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. Glass wool treated with phosphoric acid is highly advantageous as it prevents usage of more amount of glass wool for metal column tubing. 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. Glass wool treated with phosphoric acid is highly suitable for the analysis of free fatty acids (FFA).
Wool plugs are often used in GC inlet liners to improve sample vaporization, and/or to keep non-volatile material from entering the column. They can also be used in packed GC columns, solvent desorption tubes, thermal desorption tubes, and purge traps to retain adsorbent beds.
Application
Glass wool column maybe used for the separation of lymphocytes in human blood.
Other Notes
Phosphoric Acid Treated for acidic compounds such as barbiturates, free fatty acids, etc.
