    Hollow Cathode Lamp and Nebulizer Double Beam AAS Atomic Absorption Spectrophotometer
    Introduction of Atomic Absorption Spectrophotometer
    Atomic absorption spectroscopy (AAS) is based upon the principle that free atoms in the ground state can absorb light of a certain wavelength. These very specific wavelengths give the technique excellent specificity and detection limits in the AAS analysis.

    Features of Atomic Absorption Spectrophotometer AA2300
    1.Stability: Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature (with the function of the eliminating the affection of wavelength drift on the base line stability) and electronic circuit drift so as to reach a good basic line stability.
    2.Quickly: The cathode lamp needs not be pre-heated for long time and sample can be analyzed immediately. It is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples.
    3.High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.
    4.Long-life and anti-corrosive atomization system:The burner is made of new type titanium alloys, anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.

    Applications of Atomic Absorption Spectrophotometer
    Atomic absorption spectroscopy is an extremely important analytical method in the field of analytical chemistry. It has been widely used in metallurgy, food, agriculture, chemical industry, environmental protection and materials science. At present, atomic absorption spectrophotometer has become one of the tools for metal element analysis and trace analysis.
