What is a spectrum analyzer?
Since 1980s, photoelectric direct reading spectrometer has been introduced into China's foundry industry as an analysis method for chemical composition control in smelting process, and gradually replaced the traditional wet chemical analysis method in China. Up to now, it has been developed to small and medium-sized enterprises, and spectral analysis is gradually combined with furnace analysis. The foundry production line imported from abroad was equipped with special spectral analysis equipment, which entered China as a complete set of equipment. This is the inevitable result of stricter quality control requirements in foundry industry, and it is also the advantage of photoelectric direct reading spectral analysis itself that determines that this technology has been enduring for 50 or 60 years since it came out 1945.
Principle of spectrum analyzer
The principle adopted by atomic emission spectrometry is the direct gasification of arc (or spark) at high temperature, which excites the elements in the sample to emit the characteristic spectral lines of each element from the solid state, and these characteristic spectral lines are divided by grating and become "spectra" arranged by wavelength. The characteristic spectral lines of these elements are subjected to analog-to-digital conversion by photoelectric conversion devices, and then processed by computer to print out the percentage content of each element.
Beginner's guide
Want a spectrum analyzer, in addition to looking for information through Baidu, you also need to find a brand manufacturer for a detailed understanding. Otherwise, it will always break if you buy it back at a high price. Even if it is repaired, it will not only delay the progress of the enterprise, but also consume the wages of employees. So after consulting clearly, you can not only understand the basic functions of spectrum analyzer, but also have unexpected gains ~
