Connecting device, for coupling capillaries, e.g. in gas chromatograph, comprises glass dome and swivel nut for bringing graphite sleeve seal against dome, metal holder on glass dome, and connections on metal holder

摘要

Connecting device (1) comprises a glass dome (4) and a swivel nut (5) for bringing a graphite sleeve seal (6) against the glass dome, a metal holder (2) on the glass dome, and connections (3) on the metal holder. An independent claim is also included for a process for exchanging the capillaries (7, 10, 11, 13) when using the above connecting device. Preferred Features: The capillaries (13) lead to detectors operating at atmospheric pressure.
