ABSTRACT:
Through the intentional introduction of dopants into a glass structure by utilizing a procedure such as is involved in the modified chemical vapor deposition technique and through subsequent drawing of this structure into capillary tubes, a body is formed that is useful for chromatographic processes. For example, the production of an alumina-doped tube allows selective chromatographic separation of unsaturated organic compounds.
