AAS Atomic Absorption Spectrophotometer For Trace Metal Analysis
AA2300
Introduction of Atomic Absorption Spectrophotometer
AAS (Atomic Absorption Spectrophotometer), analyzes metal elements based on the effect of atomic vapor in
the ground state of the substance on the absorption of
characteristic radiation. It can sensitively and reliably determine
trace or trace elements. The AAS is mainly composed of 4 parts:
light source, atomizer, spectroscopic system, and detection system.
This type of instrument has the advantages of simple structure, low
cost, high sensitivity, etc.

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
Atomic absorption spectrometer has been widely used in the analysis
of macro and micro trace elements in metallurgy, geology, mining,
petroleum, light industry, agriculture, medicine, health, food,
environmental monitoring and etc.
