  • Fast response thermochromatographic capillary columns
    Patent number: 4726822
    Abstract: A thermochromatographic column has a fused silica capillary with a high temperature chemically inert polymer coating thereon supporting a thin heater film formed by the deposition of either a high resistance metallic compound auto-catalytically from a solution of the compound or a nichrome film sputtered onto the polymer clad capillary tubing. The electrical contacts to the heater film may be either resistance welded thereto or the electrically conductive wires may be attached to the capillary body and integrated into the heater film during the deposition of the heater film. An outer layer of an electrically insulating material is applied to the heater film to electrically isolate the heater film and to protect the heater film from damage.
