Chromatographic sample introduction end connection, the other end of the hard tube is used to be connected with shuttle.
Preferably, the hard tube includes the first hard tube and the second hard tube, and first hard tube and the second hard tube are angled to be connected
Connect.
Preferably, the angle between first hard tube and the second hard tube is 10-90 °.
Preferably, the support includes base, vertical bar and geometrical clamp, and the vertical bar is arranged on base, described
Geometrical clamp is used to hard tube being fixed on vertical bar.
Preferably, the geometrical clamp is spring clip.
Preferably, first hard tube and the second hard tube are respectively glass tube.
Preferably, the flexible pipe is polyfluortetraethylene pipe.
By above-mentioned technical proposal, the hard tube that the utility model is used can be easily inserted into container, and passes through branch

Brief description of the drawings
Accompanying drawing is to be further understood for providing to of the present utility model, and constitutes a part for specification, and following
Embodiment be used to explain the utility model together, but do not constitute to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is the schematic diagram of the sampling device of liquid chromatograph.
Description of reference numerals
1 flexible pipe, 2 hard tubes, 3 supports, 4 sampling valves.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
The utility model provides a kind of sampling device, as shown in figure 1, including flexible pipe 1, hard tube 2, support 3, sampling valve 4, institute
The one end for stating flexible pipe 1 is connected with one end of the hard tube 2, and the other end of the flexible pipe 1 is used for the sample introduction end with liquid chromatograph
Connection, the other end of the hard tube 2 is used to be connected with shuttle, and the sampling valve is arranged on hard tube, and the support 3 is used for
Fixed hard tube 2.
Hard tube 2 samples from shuttle and is delivered to flexible pipe 1, and flexible pipe 1 to liquid chromatograph, can adjust sample delivery
The sampling valve 4 on hard tube 2 is saved, to control sample introduction speed.
Hard tube 2 includes the first hard tube and the second hard tube, and connection is at an angle of between first hard tube and the second hard tube, wherein
The position and material of first hard tube and the second hard tube are all without particular/special requirement, as long as angled connection, for example the first hard tube can
To be connected with flexible pipe, the second hard tube can be connected with shuttle.
Angle between first hard tube and the second hard tube can be 10-90 °, it is preferable that can be 90 °.
