A liquid chromatography distributor

Abstract

The invention relates to a liquid distribution device, especially suitable for uniform distribution of liquid, in particular to a liquid chromatography distributor. In order to improve the liquid distribution uniformity of the liquid chromatography distributor, the invention discloses a liquid chromatography distributor. The liquid chromatography distributor includes an upper distribution plate and a lower distribution plate; the upper distribution plate is provided with a central circular groove and a plurality of split flow grooves, the central circular groove is located at the center of the upper distribution plate, the The distribution grooves extend along the diameter direction of the upper distribution plate and a plurality of the distribution grooves are distributed sequentially along the circumferential direction, and one end of the distribution grooves close to the center of the upper distribution plate communicates with the central circular groove; the lower distribution plate is provided with There are a plurality of liquid distribution holes, and the plurality of liquid distribution holes are sequentially distributed along the circumferential direction and communicated with the distribution groove. The liquid chromatography distributor of the present invention can improve the distribution uniformity of the solution, reduce the generation of channel flow, drift flow and wall flow phenomenon, and improve the mass transfer efficiency.

Description

technical field [0001] The invention relates to a liquid distribution device, especially suitable for uniform distribution of liquid, in particular to a liquid chromatography distributor. Background technique [0002] The liquid chromatography distributor is one of the most critical components of the liquid chromatography column. It is installed on the upper end of the chromatography column packing and is used to distribute the solution to the surface of the packing to form the initial distribution of the solution. The liquid chromatography distributor directly affects the contact distribution between the solution and the filler, and affects the initial distribution of the solution. Therefore, the liquid distribution effect of the liquid chromatography distributor is very important to the efficiency of liquid mass transfer in the chromatography column. [0003] At present, the most commonly used liquid chromatography distributors in liquid chromatography columns are designed...

Problems solved by technology

At this time, since the liquid chromatography distributor adopts a single-point liquid inlet in the middle, the solution is freely dispersed in the filler centered on the position of the middle hole to the surroundings, so that not only will there be a single point in the vertical section. The pressure peak will make the packing uneven, and there will be channel flow, bias flow, and wall flow, which will affect the uniformity of the solution on the packing surface.
