Embodiment Construction
[0013] The present invention will be described in detail below with reference to the drawings and embodiments.
[0014] Such as image 3 As shown, the present invention is an improvement based on the existing manual operation flow path. The present invention includes solvent bottle 1, pipeline 2, infusion pump 3, pipeline 4, six-way valve 5, In addition to pipeline 6, separation element 7, pipeline 8, detector 9, pipeline 10, collector 11, and sample bottle 12, the main feature is the addition of two three-way valves 13, 14 and a plunger pump 15. The collector 11 is a collector 11 that combines sampling and collection. Among them, the three ports of the first three-way valve 13 are respectively connected to the solvent bottle 1 through the pipeline 16, the six-way valve 5 through the pipeline 17, and the plunger pump 15 through the pipeline 18; the second three-way valve 14 The three ports are connected to the detector 9 through the pipeline 10, the sampling collector 11 through...

The invention relates to an automatic flow-path separation device comprising a solvent bottle, a transfer pump, a six-way valve, a resolution element, a collector, a sample bottle, a displacement pump and a waste liquid bottle which are connected by pipelines in sequence. The automatic flow-path separation device is characterized by comprising two three-way valves, wherein three ports of the first three-way valve are respectively connected with the solvent bottle, the six-way valve and the displacement pump by pipelines; three ports of the second three-way valve are respectively connected with the collector, the resolution element and the waste liquid bottle by pipelines; and the six-way valve is directly connected with the collector by a pipeline. The automatic flow-path separation device is only provided with two three-valves, thereby having simple structure and reduced cost compared with the prior flow-path separation device; and the automatic flow-path separation device automatically completes the five processes of quantitative sampling, cleaning, separation, collecting and discharging of samples by controlling the switch of the two three-valves and the six-way valve and by controlling the displacement pump and the sample collector. The invention enhances the repeatability precision and reduces the production cost and daily maintenance difficulty of an appliance.
Description
Technical field [0001] The invention relates to a separation flow path device used in the separation and preparation of biological or chemical samples, and particularly relates to an automatic separation flow path device. Background technique [0002] Existing ordinary separation flow path device (take chromatograph as an example, such as figure 1 (Shown) mainly includes solvent bottle 1, infusion tube 2, infusion pump 3, infusion tube 4, six-way valve 5, infusion tube 6, separation element 7 (chromatographic column), infusion tube 8, detector 9, and infusion Tube 10, collector 11, sample bottle 12, etc. In the analysis process, sample introduction and collection are generally cumbersome manual operations, the analysis efficiency is low, and the repeatability is affected by the proficiency of the experimenter. However, the existing automatic separation flow path device has a complicated structure. [0003] The applicant proposed an invention patent named "An Automatic Separation ...
