Abstract
The utility model relates to experimental equipment, in particular to a microinjector for liquid chromatogram. The microinjector comprises a needle cylinder, a needle head and a push rod, wherein a support is arranged on the outer side of the needle cylinder, a rotating shaft is arranged at the top of the support, the rotating shaft is connected with a magnifier frame, and a magnifier is embedded into the magnifier frame. By adopting abovementioned structures, when the microinjector is used, the magnifier is placed on the outer side of the needle cylinder through rotation of the rotating shaft, a scale on the needle cylinder is observed through the magnifier, and the feeding accuracy is improved, so that success of an experiment is ensured.
Description
Technical field
The utility model relates to a kind of experimental facilities, is specifically related to a kind of phase chromatography-use micro syringe.
Background technology
Liquid chromatography is a chromatographic important branch; With liquid is moving phase; Adopt the high pressure transfusion system, the moving phases such as mixed solvent, damping fluid that will have single solvent or the different proportion of opposed polarity pump into the chromatographic column that stationary phase is housed, in post each composition separated after; Get into detecting device and detect, thereby realize analysis sample.
During the liquid chromatography experiment, need to adopt micro syringe that sample is injected, be provided with scale on the general micro syringe; But because the volume of micro syringe own is just little; Scale value of mark is very little on it, and the user reads difficulty in use, thereby causes error experimentally.
Summary of the invention
To many weak points that existing micro syringe exists, the utility model provides a kind of experimental facilities, is specifically related to a kind of phase chromatography-use micro syringe; This micro syringe comprises syringe; Syringe needle and push rod have support in the syringe arranged outside, and a top of the trellis is provided with rotating shaft; Be connected with the amplification picture frame in the rotating shaft, amplify picture frame and be embedded with magnifier; Adopt the micro syringe of this structure, can the rotation of magnifier through rotating shaft be placed the syringe outside during use, observe the scale on the syringe, improve the accuracy of sample introduction, thereby guarantee the success of testing through magnifier.
The concrete technical scheme that the utility model adopted is: a kind of phase chromatography-use micro syringe comprises syringe, syringe needle and push rod; In the syringe arranged outside support is arranged; Prop up top of the trellis and be provided with rotating shaft, be connected with the amplification picture frame in the rotating shaft, amplify picture frame and be embedded with magnifier; Wherein said support optimum is arranged on top, the syringe outside, and said syringe is provided with scale.
After adopting this design; Can the rotation of magnifier through rotating shaft be placed the syringe outside during use, the user just can be through the scale on the magnifier observation syringe, when carrying out sample injection operation like this; Can be clearly seen that the variation of scale; Thereby the injection rate IR of the propelling degree of control push rod and then control sample directly leans on macroscopic mode to improve the accuracy of sample introduction than existing, thereby guarantees the success ratio and the reliability of testing.
Wherein said support is a L bracket; Can rotating shaft be arranged on easily the front end of a top of the trellis like this; With use that makes things convenient for magnifier and the use that can not influence syringe; Can also be easily when not using with magnifier go to syringe above, convenient to operations such as syringe clean.
In sum, adopt the micro syringe of this structure, can the rotation of magnifier through rotating shaft be placed the syringe outside during use, observe the scale on the syringe, improve the accuracy of sample introduction, thereby guarantee the success of testing through magnifier.
Description of drawings
Fig. 1 is the structural representation of the said micro syringe of the utility model;
Fig. 2 is the structural representation of said micro syringe support of the utility model and rotating shaft
1 is syringe among the figure, and 2 is push rod, and 3 is support, and 4 are rotating shaft, and 5 is magnifier, and 6 for amplifying picture frame, and 7 is syringe needle.
Embodiment
A kind of phase chromatography-use micro syringe comprises syringe 1, and syringe needle 7 and push rod 2 have support 3 in syringe 1 arranged outside, and support 3 tops are provided with rotating shaft 4, is connected with in the rotating shaft 4 to amplify picture frame 6, amplifies picture frame 6 and is embedded with magnifier 5.
Said support 3 is a L bracket; Said syringe 1 is provided with scale.
Can the rotation of magnifier through rotating shaft be placed the syringe outside during use; The user just can observe the scale on the syringe through magnifier like this; When carrying out sample injection operation, can be clearly seen that the variation of scale, thus the injection rate IR of the propelling degree of control push rod and then control sample; Directly lean on macroscopic mode to improve the accuracy of sample introduction than existing, thereby guarantee the success ratio and the reliability of testing.
