Abstract
The utility model discloses a sample injection device for a mass spectrograph. The sample injection device is provided with a three-way connector, the three-way connector is respectively connected with the mass spectrograph, a liquid phase pipeline and an injection pump pipeline, and two switching valves for respectively controlling the liquid phase pipeline and the injection pump pipeline are arranged on the three-way connector. Since the liquid phase pipeline is fixedly connected with the injection pump pipeline, the three-way connector is not required to be assembled and disassembled frequently, and the rapid switching for individual sample injection or synchronous sample injection of the two pipelines is realized, therefore, the experimental time is saved, the liquid leakage problem caused by poor connecting due to repeated assembly and disassembly is avoided, the loss or damage of a connecting part is also avoided, and a test result can be obtained more rapidly and accurately.
Description
Technical field
The utility model relates to the accessory of precision instrument, specifically, is a kind of mass spectrometric sampling device.
Background technology
At present, before the work of mass spectrometer sample introduction, need to inject sample.Owing to injecting different samples, when after liquid phase pipeline sample introduction and syringe pump pipeline while sample introduction, carrying out again liquid phase pipeline or the independent sample introduction of syringe pump pipeline, need dismounting to connect the triple valve of two pipelines, again connect again simultaneously triple valve when sample introduction if will carry out again two pipelines next time.This has caused the frequent dismounting of triple valve needs, can not realize the quick switching of the sample introduction individually or simultaneously of liquid phase pipeline or syringe pump sample introduction pipeline, loss or the damage of the link caused due to frequent disassembling pipe, perhaps cause because connecting the bad leakage problem caused, often cause experiment not carry out smoothly.
Summary of the invention
The utility model has overcome above-mentioned shortcoming, has proposed a kind of sample injection apparatus for mass spectrographs.
Purpose of the present invention is exactly to have avoided connecting the frequent dismounting of two pipeline triple valves, and can realize liquid phase pipeline or the injection pipeline sample introduction individually or simultaneously, loss or the damage of the link caused because of frequent disassembling pipe have been avoided, perhaps cause because connecting the bad leakage problem caused, saved experimenter's operating time, guaranteed carrying out smoothly of experiment, and saved and changed the link cost damaged.
The utility model solves its technical problem and takes to such an extent that technical scheme is:
This sampling device has a three-dimensional connector, and this three-dimensional connector is connected with mass spectrometer, liquid phase pipeline and syringe pump pipeline respectively, on the three-dimensional connector, is provided with two transfer valves of controlling respectively liquid phase pipeline and syringe pump pipeline.The common selection of three-dimensional connector is triple valve.
Transfer valve can be manual control, controller also can be set and automatically control.Controller used can be PLC controller (Programmable Logic Controller).When liquid phase pipeline needs sample introduction, open the liquid phase pipeline transfer valve; When the injection pipeline needs sample introduction, open the syringe pump pipeline switching valve.Also can open simultaneously these two transfer valves, simultaneously from liquid phase pipeline and syringe pump pipeline to the mass spectrometer sample introduction.
The utility model has the advantage of: because liquid phase pipeline is fixedly connected with the syringe pump pipeline, no longer need frequent dismounting three-dimensional connector, two independent sample introductions of pipeline or the quick switching of sample introduction have simultaneously been realized, therefore saved experimental period, avoided connecting the bad leakage problem caused because of repeated disassembled and assembled, also avoided due to frequent disassembling pipe cause and loss or the damage of link are conducive to obtain rapidly and accurately test result.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1. mass spectrometer; 2. triple valve; 3. liquid phase pipeline; 4. syringe pump pipeline; 5. liquid phase pipeline transfer valve; 6. syringe pump pipeline switching valve.
Embodiment
As shown in Figure 1, this sampling device has a triple valve 2, this triple valve 2 is connected with mass spectrometer 1, liquid phase pipeline 3 and syringe pump pipeline 4 respectively, is provided with liquid phase pipeline transfer valve 5 and syringe pump pipeline switching valve 6 changing on triple valve 2, controls respectively the sample introduction of liquid phase pipeline 3 and syringe pump pipeline 4.
When liquid phase pipeline 3 needs sample introduction, open liquid phase pipeline transfer valve 5; When syringe pump pipeline 4 needs sample introduction, open syringe pump pipeline switching valve 6. and also can open simultaneously these two transfer valves, simultaneously from liquid phase pipeline 3 and syringe pump pipeline 4 to mass spectrometer 1 sample introduction.
The utility model no longer needs frequent dismounting triple valve, can the company of realization the quick switching of an independent sample introduction of pipeline, finally realized accurate sample introduction, do not obscured, be conducive to obtain rapidly and accurately test result.
Above sample injection apparatus for mass spectrographs provided by the utility model is described in detail, applied specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment is just be used to helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description section is interpreted as restriction of the present utility model.
