Abstract
A quick-cool coiled chromatographic column module and a gas chromatograph that incorporates one or more of the quick-cool coiled chromatographic column modules. The module includes a chassis, a cooling radial fan, a coiled chromatographic column, and a temperature sensor. The coiled chromatographic column is captured by the chassis so as to radially encircle the cooling radial fan at a radially spaced distance from the rotatable fan blades. Operation of the fan is controlled by the temperature of the coiled chromatographic column sensed by the temperature sensor.
Claims18
A quick-cool coiled chromatographic column module, comprising:
- (a) a chassis,
- (b) a cooling radial fan having rotatable fan blades that rotate about an axial axis secured to the chassis,
- (c) a coiled chromatographic column captured by the chassis so as to radially encircle the cooling radial fan at a radially spaced distance from the rotatable fan blades, and
- (d) a temperature sensor for sensing the temperature of the coiled chromatographic column and transmitting a signal indicating the sensed temperature of the coiled chromatographic column to an on-off controller.
