Abstract

The utility model discloses an air-phase chromatogram meter with a mini converter, comprising a chromatogram column, a hydrogen-flame checking device and a converter arranged between the chromatogram column and the checking device. The utility model is characterized in that a heated used by both the checking device and the converter is arranged on the checking device; the main body of the converter is a column-shaper converting pole in which a nickel catalyst is filled, and one end of the converting pole is a converter nozzle which extends into the inside of the checking device and the other end is connected with the chromatogram column. A hydrogen inlet adapter communicated with the converting pole is fixed above the joint-part between the converting pole and the chromatogram column along the radial direction. The column-shape design of the converting pole can improve the peak form of carbon monoxide, carbon dioxide and firedamp, and can reduce the occupying space of the converter and lead the structure compact. And the checking device and the converter use the same heater, and then the space can be reduced and the energy can be saved and the cost also can be reduced.

Description

Gas chromatograph with miniature reburner
Technical field
The utility model belongs to the gas chromatographic analysis field, relates in particular to gas chromatographic analysis device.
Background technology
Gas chromatograph with gas as moving phase (carrier gas), be widely used in the quantitative test work of gas and volatile liquid substance and solid sample, can give the concentration of carbon monoxide, carbon dioxide, methane in the gas well gas of reporting where deposits are found, the transformer oil by gas chromatograph, to prevent that carbon monoxide, methane concentration from reaching certain level and setting off an explosion.And reburner is mainly used in the quantitative test of carbon monoxide, carbon dioxide, methane gas composition in whole chromatograph.The gas chromatograph of Chu Xianing mainly adopts the reburner of U font structure in the market, need the well heater of a special use that reburner is heated, the reburner overall volume is bigger, take the bigger volume of instrument, the inner space of U font structure is bigger simultaneously, directly causes consuming more nickel catalase.
Summary of the invention
The technical matters of the required solution of the utility model is to provide a kind of gas chromatograph with miniature reburner, defective such as bulky, loosely organized and nickel catalase consumption is more with the reburner that overcomes prior art.
The technical solution of the utility model is:
A kind of gas chromatograph with miniature reburner, comprise chromatographic column, hydrogen flame detector and be installed between reburner, it is characterized in that the shared well heater of detecting device and reburner is installed on the detecting device; The reburner main body is inner cylindrical conversion bar of filling the nickel catalase, transforming bar one end is the reburner spout that stretches into detecting device inside, transform the bar other end and dock, above conversion bar and chromatographic column butted part, radially be fixed with a hydrogen inlet joint that communicates with the conversion bar with chromatographic column.
Described conversion bar is fixed together by graphite gasket and sealing nut and detecting device.
Described conversion bar is a stainless-steel tube, and internal diameter is 1.7mm, long 60mm.
Described hydrogen inlet joint is weldingly fixed on argon arc welding with transforming bar, and the hydrogen inlet joint communicates with the conversion bar.
The beneficial effects of the utility model are: the design of cylindrical conversion bar not only makes the peak shape of carbon monoxide, carbon dioxide, methane improve, reburner takies volume and reduces, it is compact that structure becomes, but also use two well heaters to be improved to and the shared well heater of detecting device respectively detecting device and reburner in original technology, both reduced the space, also saved the energy, in addition, because reducing of reburner internal diameter, fill the also corresponding minimizing of nickel catalase consumption within it, thereby reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structure of reborner synoptic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As figure, the utility model comprises chromatographic column 1, hydrogen flame detector 2 and is installed in reburner 3 between chromatographic column 1, the hydrogen flame detector 2, it is characterized in that, detecting device 2 is provided with the shared well heater 4 of detecting device 2 and reburner 3; Reburner 3 main bodys are inner cylindrical conversion bar 5 of filling the nickel catalase, transforming bar 5 one ends is the reburner spout 6 that stretches into detecting device 2 inside, transforming bar 5 other ends docks with chromatographic column 1, above conversion bar 5 and chromatographic column 1 butted part, radially be fixed with a hydrogen inlet joint 7 that communicates with conversion bar 5.
When chromatograph was worked, sample at first was admitted to injector, was carried by carrier gas then and entered chromatographic column 1 (packed column or capillary column).Since in the sample each component in chromatographic column moving phase and stationary phase between distribute or the difference of adsorption coefficient, under the flushing of carrier gas, each component distributes in two-phase intercropping repeated multiple times, make each component in chromatographic column, obtain separating, gas after separated enters reburner 3, by the nickel catalase in the reburner 3 with the carbon monoxide in the gas, carbon dioxide is converted into methane, need simultaneously reburner 3 is fed hydrogen, subsequently on the hydrogen flame detector 2 of gas chromatograph according to the physicochemical characteristics of component, each component is detected in order, and detect carbon monoxide, the carbon dioxide response, response according to component calculates concentration again, in whole process, reburner 3 and detecting device 2 provide energy by well heater 4.
