Introduction of Atomic Absorption Spectrophotometer
The AA2300 series atomic absorption spectrophotometer is the fifth generation of atomic absorption spectrometers developed by wayeal. The combination of a fully reflective dual beam beam splitting system, a new lens coating process, an optimised fourth generation Czerny-turner optical path design and an integrated optical platform design delivers extremely high luminous flux while providing excellent performance with low gain and high signal to noise ratio, greatly improving sensitivity and stability.

Applications of Atomic Absorption Spectrophotometer
Atomic Absorption Spectrophotometer is now widely used in industry, agriculture, biochemistry and pharmaceuticals, geology, metallurgy, food inspection and environmental protection. The atomic absorption spectroscopy has become one of the most powerful means of metal element analysis. And in many areas has been used as a standard analytical method such as plant analysis in agriculture, fertilizer analysis, feed analysis; biochemistry and pharmacology in the analysis of body fluids, viscera and specimen analysis, drug analysis; metallurgy in the analysis of iron and steel, alloy analysis: geochemistry in the analysis of water quality, analysis of atmospheric pollutants, soil analysis, rock mineral analysis; food trace element analysis.
