High-pressure infusion pump in HPLC (high performance liquid chromatograph) for teaching

Abstract

The invention relates to the technical field of liquid chromatographs, in particular to a high-pressure infusion pump in an HPLC (high performance liquid chromatograph) for teaching. The high-pressure infusion pump comprises a visual pump head, a pump plunger push part, a cam part, a power output part and a visual outer cover, wherein the power output part, the cam part and the pump plunger push part are arranged in the visual outer cover; a visual upper cover plate is arranged above the cam part; the visual pump head comprises a visual pump head body; the visual pump head body, the visual upper cover plate and the visual outer cover are made of transparent materials. In the whole working process of the high-pressure infusion pump, an operator can know the mechanical structure and the working principle of the high-pressure infusion pump fully and directly by the aid of the visual pump head body, the visual upper cover plate and the visual outer cover, and teaching can get twofold results with half effort; besides, the high-pressure infusion pump has the advantages of high practicability, small size, high compatibility, low cost and the like, due functions of the high-pressure infusion pump are guaranteed, the requirement that everyone has a pump in experimental classes in colleges can be met, and the expectation for the teaching quality is improved.

Description

technical field [0001] The invention relates to the technical field of liquid chromatographs, in particular to a high-pressure infusion pump in high-performance liquid chromatographs for teaching. Background technique [0002] In the current field of analytical instruments, the development and application of liquid chromatography is making great progress. In terms of higher education, the education and application of high-performance liquid chromatography analysis methods has become a compulsory course for colleges and universities in chemistry and chemical engineering, application, medicine, medicine, environmental protection, food safety and other majors. As one of the core components of high-performance liquid chromatography, the high-pressure infusion pump must be deeply understood by both teachers and students. [0003] But as far as the current reality is concerned, most of the teaching instruments are imported, and the price of these instruments is very expensive, co...
