Principle and characteristics of liquid chromatograph diode array detector

High performance liquid chromatography diode array detector ultraviolet light emitted from a deuterium lamp through the achromatic lens system, is irradiated on the flow cell, a slit after irradiating a light beam on a holographic grating, the spectral dispersion by a set of photodiodes arrival On the array, spectral information was measured in a few milliseconds. Compared to conventional spectral detectors, the relative position of the splitting system and the sample cell of the secondary array detector is exactly opposite, so this optical path structure is called an "inverted optical" system.

The secondary array tube detector first passes the speed of light through the flow cell and then splits it by the beam splitting system so that all wavelengths of light are detected simultaneously at the diode array detector. Its signal is obtained by electronically scanning quickly, and the scanning speed is very fast, far beyond the peak speed of the chromatogram, so it can detect the absorption spectrum of each moment of the chromatographic effluent, and obtain the three-dimensional time - chromatographic signal. - Absorption spectrum.

The characteristics of the secondary array tube detector are:

1 can perform full wavelength detection, one injection can detect all components in different absorption wavelengths in the sample;

2 high spectral resolution, can detect the purity of the chromatographic peak;

3 high sensitivity;

4 linear range is wide;

5 The noise of the baseline is small.

The above engineers from the Liquid Chromatography Division of Shandong Luchuang Analytical Instrument Co., Ltd. have sorted out the knowledge about the liquid chromatograph diode array detector. I hope that you will be helpful when choosing to use the liquid chromatograph.

Our wooden working machine use advanced technique to make motor. So there is higher & stronger power. Using longevity is more longer. Little sparkling, perfect gear noise and more accurate cutting precision.
Circular Saw have plastic motor house and aluminium motor house. Big additional handle is more safety for using. Size is 7`,8`,9`,10`,12`.
Miter saw has more accurate adjustable precision.8427U is 12` biggest blade. Vertical and level adjustable degree is 0-45degree. More higher Input power. Size is 10`,12`.
Ordital grinder size is 93x185mm, 110x100mm
Electric trimmer has higher power. Make the working is more easy and more happy.
Corner assemblying machine give more professional tools to use.
Electric Chain Saw have 1600W high power. Easy user. Don`t like gasoline Chain Saw so complex operation.

Safety rules
1. Pls read the operation manual carefully before using.
2. Before installing the blade must check the machine no-load about one minute. After installing the blade. Check the blade is installed safety and work no-load normally. If there is abnormal, pls remove the blade and install again.
3. Don`t use any broken blade. Before install, must check the blade is safe and no broken.
4. Finishing working, pls take off the power quickly.
5. Keep work area clean.
6. Finishing working, clean and pack the machine and blade. Maintenance your working machine.
