Abstract
The utility model relates to a capillary conducting device, and particularly relates to a capillary guide pipe of a gas chromatograph. The capillary guide pipe of the gas chromatograph comprises a first conducting part, a second conducting part and a transition connecting part, wherein the first conducting part is of a hollow cylinder body, the second conducting part is of a hollow cylinder body, and the first conducting part is connected with the second conducting part through the transition connecting part. The capillary guide pipe is capable of enabling a capillary chromatographic column to smoothly enter the gas chromatograph, and prevents the capillary chromatographic column from being broken by extrusion of the wall surface, thereby having the advantages of good conduction and protection of the capillary chromatographic column.
Description
technical field:
The utility model relates to a kind of kapillary conducting device, relates in particular to a kind of gas chromatograph kapillary conduit.
background technology:
At present, gas chromatograph capillary chromatographic column conduit is a kind of hollow cylinder copper pipe, it and gas chromatograph internal communication, this hollow cylinder copper pipe internal diameter size is identical with capillary chromatographic column external diameter size, capillary chromatographic column just forms shaft hole matching with conduit, and capillary chromatographic column passes conduit and enters gas chromatograph inside.Existing capillary chromatographic column catheter diameter is very little, identical with capillary chromatographic column external diameter size, so capillary chromatographic column penetrates in catheter procedure, because catheter diameter is little, capillary chromatographic column is easily subject to the extruding of conduit wall and breaks, can not be very level and smooth enter gas chromatograph inside by conduit.
utility model content:
Technical problem to be solved in the utility model is to provide a kind of gas chromatograph kapillary conduit; the described level and smooth conduit that passes smoothly of capillary chromatographic column that can make enters gas chromatograph inside; and avoided capillary chromatographic column to be subject to the extruding of conduit wall and broken, play conducting and protective effect to capillary chromatographic column.
According to technical matters to be solved, the technical solution of the utility model is as follows:
A kind of gas chromatograph kapillary conduit, kapillary conduit comprises the first conducting portion, and the first conducting portion is shaped as hollow cylinder, and the internal diameter of the first conducting portion is identical with the external diameter of capillary chromatographic column; Kapillary conduit also comprises the second conducting portion and transition connecting portion, and the second conducting portion is shaped as hollow cylinder, and the internal diameter of the second conducting portion is greater than the external diameter of capillary chromatographic column; The internal diameter of transition connecting portion large port is identical with the internal diameter of the second conducting portion, and the internal diameter of transition connecting portion portlet is identical with the internal diameter of the first conducting portion; The first conducting portion is connected with the second conducting portion by transition connecting portion.
Preferably, described transition connecting portion be shaped as conical hollow right cylinder.
Preferably, described transition connecting portion be shaped as hollow cone.
Preferably, the connected mode of the first conducting portion, transition connecting portion and the second conducting portion is for being fixedly connected with.
Preferably, the connected mode of the first conducting portion, transition connecting portion and the second conducting portion is for being flexibly connected.
Preferably, the first conducting portion, then is flexibly connected with the second conducting portion for being fixedly connected with the connected mode of transition connecting portion.
Preferably, the first conducting portion, then is fixedly connected with the second conducting portion for being flexibly connected with the connected mode of transition connecting portion.
The utility model beneficial effect compared to existing technology:
The utility model is owing to having increased the second conducting portion and transition connecting portion; can make the level and smooth the utility model that passes smoothly of capillary chromatographic column enter gas chromatograph inside; avoid capillary chromatographic column to be subject to the extruding of the utility model wall and broken, therefore having the utlity model has the advantage to the good conducting of capillary chromatographic column and protection.
accompanying drawing explanation:
Fig. 1 is the longitudinal cross-section schematic diagram of the utility model structure.
embodiment:
As shown in Figure 1, a kind of gas chromatograph kapillary conduit, kapillary conduit comprises the first conducting portion (1), and the first conducting portion (1) is shaped as hollow cylinder, and the internal diameter of the first conducting portion (1) is identical with the external diameter of capillary chromatographic column; Kapillary conduit also comprises the second conducting portion (2) and transition connecting portion (3), the second conducting portion (2) is shaped as hollow cylinder, the internal diameter of the second conducting portion (2) is greater than the external diameter of capillary chromatographic column, transition connecting portion (3) is shaped as hollow cone, the internal diameter of transition connecting portion (3) large port is identical with the internal diameter of the second conducting portion (2), and the internal diameter of transition connecting portion (3) portlet is identical with the internal diameter of described the first conducting portion (1); The first conducting portion (1) is connected with the second conducting portion (2) by transition connecting portion (3), and transition connecting portion (3) is fixedly connected with the second conducting portion (2), then is flexibly connected with the first conducting portion (1).
The first conducting portion 1 is the gas chromatograph kapillary conduit of existing conventional art, this conduit is a kind of hollow cylinder copper pipe, capillary chromatographic column enters into gas chromatograph inside from the port of the first conducting portion 1, in the time that capillary chromatographic column penetrates this type of conduit, capillary chromatographic column is not easy to penetrate gas chromatograph inside, is easily subject to the extruding of conduit wall and breaks.
Compared with prior art; the second conducting portion 2 and transition connecting portion 3 are inventive points of the present utility model; capillary chromatographic column enters from the port of the second conducting portion 1; through transition connecting portion 3; smoothly smoothly by the first conducting portion 1; enter into gas chromatograph inside, avoided capillary chromatographic column directly to enter the first conducting portion 1 and be squeezed and break, capillary chromatographic column is had advantages of to good conducting and protection.
Be noted that, above-described embodiment is explanation to technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, within all should being included in the desired interest field of the utility model.
