    Double Beam Atomic Absorption Spectrophotometer For Metal Analysis

    Deuterium and Tungsten Lamp Equipped Double Beam Atomic Absorption Spectrophotometer AAS for Metal Analysis
    Introduction of Atomic Absorption Spectrophotometer

    Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic absorption spectroscopy is based on absorption of light by free metallic ions.
    In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine different elements in solution, or directly in solid samples via electrothermal vaporization,and is used in pharmacology, biophysics, archaeology and toxicology research.

    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. Full-reflection dual-beam optical path, high optical path stability
    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. 8 lamp holders preheat simultaneously to improve detection efficiency
    Applications of Atomic Absorption Spectrophotometer
    Food, medicine, environment, metallurgy, agriculture and disease control
