  • Compact separating system with snap-in columns
    Patent number: 5105652
    Abstract: A fluid separation system applicable to gas chromatography includes a separating column in the form of a coiled tube in a thermally insulated enclosure. The ends of the coiled tube are connected by snap-action couplings to the outlet of an injector and the inlet of a detector which generates an electrical signal corresponding to the component of the fluid being separated. Snap action couplings also connect the thermally insulated enclosure to a thermal control system which circulates a heat exchange fluid to define the temperature in the enclosure.
