Nucleic acid protein detector independently developed and produced by Shanghai Jiapeng Technology Co., Ltd. /UV detector is a modern analytical and experimental instrument that is engaged in life science research, drug measurement, agricultural research, chemical industry, food science, colleges and universities and medical institutions today. Nucleic acid protein detector /The ultraviolet detector series products are automatic liquid chromatography separation chromatography instruments to separate UV absorbing substances. (Proteins, nucleic acids, peptides, enzymes )The principle of the ultraviolet detection device is to realize the comparison and analysis of sample component content based on the characteristics of the substance (sample) that have obvious absorption of ultraviolet light, so as to perform identification detection and content determination of sample proteins and nucleic acid substances. Directly read out optical density A The relative peak value of each peak area can be directly recorded in qualitative and quantitative analysis, and the relative mass content can be calculated. The instrument is equipped with a Jiapeng collector, a constant flow pump, a partial collector, a gradient mixer, and a chromatography column, which forms a complete set of automatic liquid chromatography separation and analysis devices. The Jiapeng brand can be combined with GE Healthcare  Laboratory-scale chromatography column interface is fully compatible and does not require any connectors to AKTA Pre-separation of equipment and other equipment systems can meet the requirements of various chromatographic analyses such as gel permeation chromatography, affinity chromatography, and ion exchange chromatography, and has an extremely high performance-price ratio.

Nucleic acid protein detector /The ultraviolet detector series products have the function of continuous detection of micro sample cells. During the column chromatography separation and analysis process, the eluent flows through the Jiapeng sample cell. The chromatography map collector can automatically draw a sample separation map (absorption peak or transmissive peak). At the same time, the distribution of the required samples in some collector test tubes can be detected, and the column chromatography process can be monitored at any time. Especially during the exploration of the experiment, the elution conditions are changed in time so as to quickly obtain a good experimental plan and finally achieve the separation of biological macromolecules. It is an ideal instrument for scientific research and production by scientific research institutions and factories and mining enterprises, and has been widely used by nationally renowned universities such as Tsinghua University, Peking University, and Fudan University.
