At present, normal dropper or the dropping funel of adopting adds along column wall, dropper mouth can slide along column wall, make eluant, eluent along column wall surrounding sample introduction, but each dynamics difference causes the speed of feed liquor and the amount of feed liquor all different, in addition each feed liquor is few and discontinuous, need repeatedly drip complex operation and poor efficiency.During with dropping funel feed liquor, eluant, eluent can only add along column wall one side, cannot easily destroy the smooth of adsorbent surface along the uniform feed liquor of inwall surrounding, is unfavorable for the separation of sample component.Be with dropper or with dropping funel all can not reach slowly, continuously, stable, do not interrupt and do not destroy the smooth feed liquor requirement of adsorbent surface.
Therefore, the necessary deficiency of prior art being improved to solve prior art.
summary of the invention:
The utility model is discontinuous in order to solve dropper liquid feeding, and complex operation poor efficiency; Dropping funel can only easily destroy the smooth of adsorbent surface along column wall one side feed liquor, is unfavorable for the separated problem of sample component and a kind of chromatographic column feeding device is provided.
The technical scheme that the utility model adopts has:
A kind of chromatographic column feeding device, this device comprises feed tube, funnel and ground liquid inlet head, feed tube one end is connected with the liquid outlet of funnel, the other end is through ground liquid inlet head, and feed tube bottom is provided with horn-like wealthy mouthful, this wealthy mouthful bottom through ground liquid inlet head and with the ground liquid inlet head structure that is connected as a single entity, in the circumferential wall of wealthy mouthful, be provided with some fluid holes, fluid hole is positioned at ground liquid inlet head below, this upper steam vent that is also provided with of wealthy mouthful, this steam vent communicates with the exhaust outlet that is arranged on ground liquid inlet head upper end; On described feed tube and between funnel and ground liquid inlet head, be provided with a water check valve.
Further design of the present utility model is:
Described wealthy mouthful of diameter is less than ground liquid inlet head base diameter.
Described ground liquid inlet head bottom maximum gauge is 24mm, and the diameter of wealthy mouthful of maximum is 18mm.
Described fluid hole is evenly arranged in the circumferential wall of horn-like wealthy mouth.
Described ground liquid inlet head is hollow shape.
The utlity model has following beneficial effect: the utility model is simple in structure, easy to operate, by adjusting be arranged on water check valve on feed tube make the interpolation of eluant, eluent reach slowly, continuously, stable, by being arranged on the fluid hole of the equidistant distribution of ground liquid inlet head bottom, make feed liquor even.
