Abstract
The utility model discloses a gas chromatograph which is characterized in that a column box consists of a box body and a top cover; a plurality of electric heating wire support rods are arranged on the upper side of the bottom of the box body; electric heating wires are wound and fixed on the electric heating wire support rods; a main shaft is fixed at a circle center of the bottom of the box body by a shaft sleeve; the lower end of the main shaft is connected with a motor; lower exhaust blades and side exhaust blades are fixed on the main shaft; a plurality of chromatographic column support rods are arranged on the lower side of the top cover; chromatographic columns are wound and fixed by the chromatographic column support rods; and gas inlet ends and gas outlet ends of the chromatographic columns are connected with a sample injector and a detector by heat resistance connecting pieces respectively. The gas chromatograph is convenient to assemble and dismount and compact in structure, the size of the chromatograph is reduced, the occupied space can be reduced, the temperature in the box body is balanced, the chromatographic columns are heated uniformly, and test results are precise.
Description
Technical field
The utility model relates to a kind of analyzing and testing equipment, relates in particular to a kind of gas chromatograph.
Background technology
Gas chromatograph is each component in mixed gas to be carried out to the instrument of analyzing and testing, very wide in aspect application such as oil, chemical industry, biological chemistry, medical and health, food industry, environmental protection.Current gas chromatograph volume is larger, takes up room large, and Portable belt, is not only confined to use in laboratory.In addition, can chromatographic column thermally equivalent be the key factor that affects testing result in post case, and uniform temperature fields degree in current gas chromatograph post case is still to be improved.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is small and exquisite, and post the temperature inside the box is even, is conducive to carry and the accurate gas chromatograph of test result.
The utility model solves the technical scheme that its technical matters adopts: a kind of gas chromatograph, comprise post case, post case consists of casing and the top cover that is sealed and matched with it, described bottom half upside is provided with some circumferential heating wire support bars, heating wire winding is fixed on heating wire support bar, and bottom half is provided with two connection terminals that are connected with heating wire two ends respectively; Bottom half circle centre position is fixed with main shaft by axle sleeve, main shaft upper end extends to casing upper end, main shaft lower end is extended bottom half and is connected with motor, is fixed with the lower air exhaust blade that is positioned at casing top and the side air exhaust blade that is positioned at bottom half on described main shaft; Described top cover downside is provided with some circumferential chromatographic column support bars, and chromatographic column is fastened by chromatographic column support bar, and the inlet end of chromatographic column is connected with the injector, the detecting device that are positioned at top cover upside by heat-resisting web member respectively with outlet side; The downside circle centre position of described top cover is provided with the bearing of a restriction main shaft upper end.
Described top cover and casing joint are provided with sealing gasket.
Described bottom half and top are equipped with water conservancy diversion packing ring, and the outside of described water conservancy diversion packing ring is interior chamfering.
The beneficial effects of the utility model are: it is integrated in functional part on casing and top cover, assembling, convenient disassembly, and compact conformation, has dwindled chromatographic volume, can reduce and take up room, and is easy to carry; In its casing, adopt lower air exhaust blade and side air exhaust blade to impel Air Flow, by water conservancy diversion packing ring, promoted flow path direction, make temperature equalization in casing, chromatographic column is heated evenly, and test result is accurate.
