1、 Product introduction

Automatic low-pressure liquid chromatography is a modern analytical experimental instrument for life science research, agricultural research, chemical industry, food science, colleges and medical institutions. Nucleic acid protein detector / ultraviolet detector is a kind of ultraviolet detection device which can separate ultraviolet absorbing substances (protein, nucleic acid, polypeptide and enzyme) in automatic liquid chromatography chromatography. Its principle is to realize the comparison and analysis of the content of sample components according to the obvious absorption characteristics of substances (samples) to ultraviolet light, so as to carry out the identification and detection of sample protein and nucleic acid substances Content determination. Jiapeng JP series automatic liquid chromatographic separation chromatograph can directly read the optical density a value, and has good wavelength accuracy and repeatability, good monochromaticity, and can directly record the relative peak value of each peak area and calculate the relative mass content in qualitative and quantitative analysis; The instrument is equipped with Jipeng collector, constant current pump, partial collector, gradient mixer and chromatographic column, which is a complete set of automatic liquid chromatography separation and analysis device. It can meet the requirements of chromatographic analysis, such as gel permeation chromatography, affinity chromatography and ion exchange chromatography, and has some performance price ratio.

Automatic low pressure liquid chromatography chromatograph 2001-a-ii has the function of continuous detection in micro sample pool. In the process of column chromatography, the eluent flows through the sample pool, and the chromatographic atlas collector can automatically draw the spectrum of sample separation (absorption peak or transmission peak), simultaneously detect the distribution of required samples in some collector tubes, and monitor the column layer at any time In the process of analysis, especially in the process of exploring the experiment, the elution conditions should be changed in time, so as to obtain a reliable experimental scheme quickly and achieve the separation of biological macromolecules.
