Wayeal AA2300 Graphite Furnace AAS Atomic Absorption Spectroscopy
Machine Atomic Absorption Spectrophotometer
Introduction of Atomic Absorption Spectrophotometer
Absorption spectroscopy is one of the most widely used techniques
employed for determining the concentrations of absorbing species
(chromophores) in solutions. It is a nondestructive technique which
biologists and biochemists and now systems biologists use to
quantify the cellular components and characteristic parameters of
functional molecules.

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 spectrometry has many uses in different areas of
chemistry such as clinical analysis of metals in biological fluids
and tissues such as whole blood, plasma, urine, saliva, brain
tissue, liver, hair, muscle tissue. Atomic absorption spectrometry
can be used in qualitative and quantitative analysis.
