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.
