  • System for manufacturing chromatographic columns
    Patent number: 5709904
    Abstract: Invention is directed to a system, i.e. method and apparatus, for manufacturing thin-walled capillary columns for use in a gas chromatographic device. The system involves the sequential filling and evacuating of the columns in a controlled environment, where the system is under the control of a microprocessor to achieve improved processing control and monitoring. The system also produces a consistant homogeneous film of polymer along the inner wall of the columns.
