Automatic liquid chromatography separation chromatography 2001 independently developed and produced by Shanghai Jiapeng Technology Co., Ltd.- B-IV It 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 /UV detector series products are automatic liquid chromatography separation chromatography 2001- B-IV Medium separation with ultraviolet 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. Jiapeng card can directly read the optical density A The value, and the wavelength accuracy and repeatability are high, the monochromaticity are good, the relative peak values ​​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 current pump, partial collector, gradient mixer, and chromatography column, which forms a complete set of automatic liquid chromatography separation and analysis devices, which can meet the requirements of various chromatography analyses such as gel permeation chromatography, affinity chromatography, and ion exchange chromatography, and has an extremely high performance-price ratio.  
Automatic liquid chromatography separation chromatography 2001- B-IV It has the function of continuous detection of micro sample cells. During the column chromatography separation and analysis, 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.
 

    Automatic liquid chromatography separation chromatography 2001- B-IV Correct use: Jiapeng automatic liquid chromatography separation chromatography is a precision instrument. The insoluble matter in the mobile phase, the precipitation of salt in the buffer, the bubbles in the mobile phase, bacteria or microorganisms in the instrument pipeline or valve will affect the life or performance of the instrument. Special attention should be paid to relevant parties during operation. Use the instrument correctly to ensure the good performance of the instrument and extend the life of the instrument.
1、After the automatic liquid chromatography separation chromatograph is finished, thoroughly clean all pipes and valves if placed the next day after use.
2、If the automatic liquid chromatography separation chromatography device is not used for a period of time, clean it with deionized water, and fill the pipeline with 20% ethanol or 0.05% sodium azide solution. For a long time, the pump, valve, detector and other entrances and outlets should be closed with a random plug to prevent the solution from evaporating. Prevent bacteria or microorganisms from growing inside the instrument pipeline valves, and pay special attention to high temperatures. It is difficult to remove after bacteria or microorganisms grow.
3、The automatic liquid chromatography separation chromatography device should be stored in a dry and ventilated environment to prevent mold or rust from the instrument. If the instrument is in a low temperature environment (Cold room or chromatography cabinet )，Do not turn off the power supply to prevent water vapor from condensing.
