Device.
Gas chromatograph is generally divided into injection port, detector, post case, circuit air-path control system.Injection port and detector
More sets can be installed, to adapt to the needs of different sample analysis, but post case only has one, it is impossible to adapt to be responsible for sample multicolumn,
The analysis requirement of more valves.
Utility model content
The utility model provides a kind of more post case systems of the more clack boxes of rapid temperature rise and drop for gas chromatograph, can be achieved more
Post, more valves work simultaneously, complete complicated analysis work.
The technical solution adopted in the utility model is：
A kind of more post case systems of the more clack boxes of rapid temperature rise and drop for gas chromatograph, including chromatograph, the chromatograph

Side is uncapped, uncapped on the side with side uncap set locking device, it is described on uncap with side uncap set heat-insulation layer.It is independently arranged
Post case can individually be controlled with clack box, be in different temperature environments, while complete multiple gases or multiple steps
Rapid analysis work.
Preferably, the detached column chamber interior wall is metal material, is provided with heating rod.By heating rod to metal inner surface
Heating, makes to be rapidly heated in independent post case.
Preferably, the detached column case includes the inner chamber for being shaped as cylinder and the inner chamber for being shaped as elliptical cylinder-shape.It is different
The inner chamber of shape is used to place different chromatographic columns, and as capillary column preferably uses cylindrical cavity, packed column preferably uses cylindroid
Shape inner chamber.
Preferably, fixed part is set in the independent clack box, for placing switching valve.
