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
