The development of atomic absorption spectrometer

China's first commercial atomic absorption spectrometer was manufactured at Beijing No. 2 Optical Instrument Factory, now Beijing Ruili Analytical Instrument Co., Ltd., Ruili Company is the largest professional manufacturer of spectral analysis instruments in China, and now develops and produces seven series. More than 70 products: atomic absorption series, atomic fluorescence spectrometer, chromatography-atomic fluorescence spectrometer, atomic emission spectrometer series, Fourier infrared series, ultraviolet/visible spectrophotometer series, microwave digestion and microwave digestion extractor series Equal spectrum analysis instrument. The company has a large-scale precision CNC machining center with advanced technologies such as optical processing, grating engraving, grating reproduction, and large reliability labs for high-low temperature, high pressure resistance and vibration for instrument inspection, providing excellent quality for the instrument. Reliable guarantee. And in 1997 took the lead through the ISO-9001 quality system certification. The company's products have not only won the bid in domestic and international bidding, but also exported to the United States, Southeast Asia, South Korea and Europe and Africa and other countries and regions, and have a high reputation at home and abroad. The company's leading products are atomic absorption spectrophotometers and atomic fluorescence spectrometers. And represents the current highest level in China. Since the production of China's first commercial atomic absorption in 1971, over 40 years, it has provided more than 40 models of more than 20,000 instruments to customers at home and abroad, and has always ranked first in China. He has won the third prize of National Science and Technology Progress Award, the National Quality Silver Award, and has won the BCEAI Gold Award many times.

The atomic absorption spectroscopy of atomic absorption spectrometry has been used since 1955 as a practical analytical method. This year Australia's A. Walsh published his famous paper 'Application of Atomic Absorption Spectroscopy in Chemical Analysis' to lay the foundation for atomic absorption spectroscopy. In the late 1950s and early 1960s, Hilger, Varian Techtron, and Perkin-Elmer introduced atomic absorption spectrometers to develop Valsi's design ideas. By the mid-1960s, atomic absorption spectroscopy began to enter a period of rapid development. The generation of electrothermal atomic absorption spectrometry instruments In 1959, the Soviet Union Lviv published the first paper on electrothermal atomization technology. The sensitivity of electrothermal atomic absorption spectrometry can reach 10-10g, which makes the atomic absorption spectrometry a step forward. The development of atomic absorption analysis instruments has promoted the continuous updating and development of atomic absorption instruments with the development of atomic absorption technology, while other scientific and technological advances have provided technical and material basis for the continuous updating and development of atomic absorption instruments. In recent years, the use of continuous light source and middle gate grating, combined with the use of light guide tube, diode array multi-element analysis detector, designed a computer-controlled atomic absorption spectrophotometer, opened up a new vision for the simultaneous determination of multi-element. The computer-controlled atomic absorption spectroscopy system simplifies the instrument structure, improves the automation of the instrument, improves the accuracy of the measurement, and makes a significant change in the appearance of the atomic absorption spectroscopy.
The spectroscopy is based on the fact that the ground state atoms of the measured element in the gas state strongly absorb the atomic resonance radiation of the element. The method has the advantages of low detection limit, high accuracy, good selectivity and fast analysis speed.
Atomic absorption spectrometry is gradually known using the principle of spectroscopy.
