Details:

Nucleic acid protein detector / ultraviolet detector is a modern analytical experimental instrument which is engaged in life science research, * * determination, agricultural scientific research, chemical industry, food science, universities 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. The optical density a value can be read out directly, and the wavelength accuracy and repeatability, monochromaticity are good, 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 Jiapeng collector, constant flow pump, partial collector, gradient mixer and chromatographic column to form a complete set of automatic liquid chromatography separation and analysis device Healthcare laboratory scale column interface is completely compatible, without any connector, it can be pre separated in AKTA and other equipment systems. It can meet the requirements of chromatographic analysis, such as gel permeation chromatography, affinity chromatography and ion exchange chromatography, and has a performance price ratio.

Nucleic acid protein detector / ultraviolet detector series products have the function of continuous detection in micro sample pool. In the process of column chromatography separation and analysis, the eluent flows through Jiapeng sample pool, and the chromatographic atlas collector can automatically draw the spectrum of sample separation (absorption peak or transmission peak), and detect the distribution of required samples in some collector tubes, and monitor it at any time In the process of column chromatography, especially in the process of exploring the experiment, the elution conditions should be changed in time, so as to obtain the experimental scheme quickly, and then to separate biomacromolecules. It has been widely used in Tsinghua University, Peking University and Fudan University.

The performance potential of HD-7N ultraviolet detector is as follows:

1. Light source: imported UV cold light source with rich spectrum and uniform intensity of each spectral line

2. At the same time, it can detect the distribution of the required samples in some collectors.

3. It can be conveniently installed in the standard chromatography freezer for the purification of unstable samples.

4. Multi interface real-time rendering chromatography (A / T; t% / T; A-T% / t double ordinate comparison);

5. Chromatographic map selection, scaling, data analysis; multi format storage (HSV, bitmap, chromatogram conversion to excel format data)

6. LED digital display of three OD value table, the user can directly read the optical density a value

7. It adopts USB / COM dual data port, which can be operated online easily. XP / win7 system is compatible.
