Abstract
The utility model is a kind of accessory of capillary chromatography instrument, the coupling arrangement of a kind of capillary chromatography instrument injection port and packed column specifically, it comprises post nut, kapillary and adapter, one end capillaceous is connected and extends with post nut, and the outer end of post nut is that one end that kapillary stretches out is provided with graphite dottle pin; The other end capillaceous is connected with steel pipe, and steel pipe is connected with adapter and extends through nut, and nut is connected with adapter by sealing gasket; Described kapillary and steel pipe are to connect by being weldingly connected; Described kapillary, steel pipe and nut are stainless steel; Described sealing gasket is metal material.The utility model has been continued to use original injection port on capillary chromatography instrument, has exempted and has reconfigured the spending that special-purpose injection port and related accessory produce, and has saved cost; The utility model is simple in structure, easy to operate, has realized packed column and has been directly installed on the effect on existing capillary chromatography instrument injection port.
Description
Technical field
The utility model is a kind of accessory of capillary chromatography instrument, is the coupling arrangement of a kind of capillary chromatography instrument injection port and packed column specifically.
Background technology
Packed column and capillary chromatographic column are the devices with identical function being used on capillary chromatography instrument, are arranged on the injection port of capillary chromatography instrument during use.Capillary chromatographic column can be directly installed on injection port, use more convenient, but capillary chromatographic column complex structure, during use, temperature can not be too low, otherwise resulting chromatographic peak circle but also wide has not only reduced post effect.Packed column is simple in structure, also temperature influence not, but packed column can not be directly installed on injection port, for packed column is installed, just must reconfigure special-purpose injection port and related accessory, and this will spend a no small expense.
Summary of the invention
The purpose of this utility model is can not be directly installed on the defect of capillary chromatography instrument injection port in order to overcome packed column, invent the coupling arrangement of a kind of capillary chromatography instrument injection port and packed column, this coupling arrangement has been continued to use original injection port on capillary chromatography instrument, exempted and reconfigured the spending that special-purpose injection port and related accessory produce, saved cost.
The utility model is realized as follows: the coupling arrangement of described capillary chromatography instrument injection port and packed column, comprise post nut, kapillary and adapter, one end capillaceous is connected and extends with post nut, and the outer end of post nut is that one end that kapillary stretches out is provided with graphite dottle pin; The other end capillaceous is connected with steel pipe, and steel pipe is connected with adapter and extends through nut, and nut is connected with adapter by sealing gasket.
Described kapillary and steel pipe are to connect by being weldingly connected.
Described kapillary, steel pipe and nut are stainless steel.
Described sealing gasket is metal material.
Good effect of the present utility model is as follows: the utility model has been continued to use original injection port on capillary chromatography instrument, has exempted and has reconfigured the spending that special-purpose injection port and related accessory produce, and has saved cost; The utility model is simple in structure, easy to operate, has realized packed column and has been directly installed on the effect on existing capillary chromatography instrument injection port.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing
In figure: 1 post nut 2 kapillary 3 adapters
4 graphite dottle pin 5 steel pipe 6 nuts
7 sealing gaskets.
Embodiment
As shown in Figure 1, the coupling arrangement of described capillary chromatography instrument injection port and packed column, comprise post nut 1, kapillary 2 and adapter 3, one end of kapillary 2 is connected and extends with post nut 1, and the outer end of post nut 1 is that one end that kapillary 2 stretches out is provided with graphite dottle pin 4; The other end of kapillary 2 is connected with steel pipe 5, and steel pipe 5 is connected and extends with adapter 3 through nut 6, and nut 6 is connected with adapter 3 by sealing gasket 7.
Described kapillary 2 is to connect by being weldingly connected with steel pipe 5.
Described kapillary 2, steel pipe 5 and nut 6 are stainless steel.
Described sealing gasket 7 is metal material.
During use, by post nut, be connected with shunting/Splitless injecting samples mouth of capillary chromatography instrument, by adapter, be connected with packed column, without reconfiguring special-purpose injection port and related accessory, whole operating process is very simple, has also saved spending therebetween.The above is only preferred implementation of the present utility model; should be understood that; those of ordinary skill for technical field; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
