Product Name: hd-2004 UV detector

Brief introduction:

Hd-2004 UV detector is widely used in biochemistry, molecular biology, * * determination, chemical engineering, food engineering, and other related colleges and research institutions. It is an indispensable instrument in chromatography.

Details:

Hd-2004 UV detector can quickly query the new quotation, pictures and technical parameters of products, or compare the performance of products. It is very convenient to use.

Hd-2004 UV detector is a kind of UV detection device with UV absorbing substances (protein, nucleic acid, polypeptide and enzyme) in liquid chromatography. It can read optical density a value directly, and record the relative peak value of each peak area directly in qualitative and quantitative analysis, and can calculate the relative content of mass; The instrument is equipped with an upper column, a constant current pump and a partial collector, etc., that is, a complete liquid chromatographic separation and analysis device is formed, which can meet the requirements of chromatographic analysis, such as gel permeation chromatography, affinity chromatography and ion exchange chromatography, and has a performance price ratio. It is widely used in modern biological research, * * determination, agricultural scientific research, chemical industry, food, colleges and medical institutions to do qualitative and quantitative analysis of samples with UV absorption. It has a micro sample cell for continuous detection, and then achieves the separation of biological macromolecules.

Product introduction:

Hd-2004 UV detector: wavelength: 220, 254, 280, 340 nm. LED digital display. Sample cell: 80 μ L, optical path: 3 mm. Range: 0-t, 0.2A.

Overview of hd-2004 UV detector:

The ultraviolet detector is a kind of ultraviolet detection device in liquid chromatography. The instrument is equipped with chromatographic column, constant flow pump and partial collector, which constitutes a complete set of liquid chromatography separation and analysis system. It can be used in modern biological research, quantitative analysis of samples with ultraviolet absorption in * * determination, agricultural scientific research, chemical industry, food and medical institutions. The main components of the instrument are imported, and all the instruments adopt LED digital display, so it is easy to use.

1. Hd-2004 UV detector is not only equipped with output 10mV recorder signal, but also equipped with output port suitable for computer integrator, so it is convenient to form chromatographic workstation system. (the signal output of computer and recorder can be carried out at the same time, or the recorder can be omitted)

2. The digital display of hd-2004 UV detector is designed as fixed light absorption, a-display computer and variable range optical absorption a display recorder. It is convenient to standardize the reading, and can also read the sensitivity of variable range according to scientific research needs, which is convenient for the detection of low concentration samples.

3. Hd-2004 UV detector adopts new imported IP28 photomultiplier tube and improved circuit structure, which makes the instrument work more stable and reliable.
