Atomic Absorption Spectroscopy (AAS)

The answer for metals or minerals identification in compounds or trace element analysis (e.g., metals, soil, waste or water drinking, bodily fluids,minerals, all sorts of chemical compounds etc) is Atomic Absorption Spectroscopy (AAS) in the field of Analytical Chemistry. The element analysis can be qualitative (determining what elements are present), and it can be quantitative (determining how much of each are present)

Working principle of Atomic Absorption Spectroscopy (AAS)

The concentration of the elements is determined through absorption of radiation as it is directly proportional to the density of the atoms in the light.

AAS Series

Flame Atomic Absorption Spectrometer

Flame atomic absorption is applied to micro and trace metallic elements test, covering over 30 elements. The instrument has simple structure, provide fast test with good repeat ability and less interference, especially suitable for testing Cu, Zn, K, Na, Au, Ag etc.

Graphite Furnace Atomic Absorption Spectrometer

Highly sensitive and is suitable for small sample volume detection especially trace and ultra-trace metallic elements test e.g. Cd, Cr, Pb, Al, Mo etc.

Advantages of Using Atomic Absorption Spectrometer

• High selectivity and sensitivity
• Fast and simple working
• Doesn’t require metals separation
