Problems solved by technology

[0005] It is very difficult to seal after several layers of metal sheets are laminated. The plane-to-plane sealing requires a very smooth and flat surface and sufficient pre-tightening force to achieve high-pressure sealing, which leads to the smoothness of the sealing surface often reaching the mirror level, and the cost Very expensive and has a high scrap rate, resulting in a significant increase in the manufacturing cost of the mixer as well as the LC

Abstract

The invention provides a mixer and a liquid chromatograph. The mixer comprises an upper cover, a lower cover and a filter. The upper cover and the lower cover are connected to form accommodation space, and the filter is arranged in the accommodation space. A plurality of mutually communicating mixing passages are formed inside the filter. At least two inflow passages penetrating through the outersurface of the lower cover are formed on the lower cover. An outflow passage penetrating through the outer surface of the upper cover is formed on the upper cover. Each inflow passage and the outflowpassage are communicated with the accommodation space. The liquid chromatograph comprises the mixer. The mixer has an extremely simple structure, the surface of the filter adopted for mixing mobile phases does not need to be subjected mirror processing, the filter surface precision requirements are low, and the whole processing and making cost of the mixer are low. When the mixer provided in the invention is applied to the liquid chromatograph, the processing and making cost of the liquid chromatograph can also be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of fluid mixing devices, in particular to a mixer and a liquid chromatograph with the mixer. Background technique [0002] The liquid chromatograph has the function of performing gradient analysis on the ratio of the mobile phase. During the gradient analysis, in order to mix two or more mobile phases uniformly, a mixer is required. [0003] The structure of the existing mixer is usually to set several metal plates with grooves etched and small holes processed on the top and bottom of the structure, and the grooves and small holes are connected by overlapping each other to form the flow of the mobile phase. path. After the unmixed mobile phase flows through these designed channels, the effect of enhanced mixing is achieved. [0004] Existing mixers have the following problems in use: [0005] It is very difficult to seal after several layers of metal sheets are laminated. The plane-to-plane sealing requir...
