AA-7020 AAS Series

AA-7020 Single Beam Graphite Furnace AAS Series.

Stock Status: Temporary sold out


AA-7020 series has unique suspension design for the optical system. Shaking of the instrument bench or change of the environmental temperature will have no effect on the instrument's stability.
It is built with 1800 lines/mm diffraction grating, which increases resolution and energy efficiency. Besides, the excellent deuterium lamp background reduction function, and self-absorption background reduction allows for more accurate calibration.
In addition, AA-7020 features an integrated flame and graphite furnace design that contains the optical system, atomizer, graphite furnace power supply and electronics all in one unit. It is a leading design in the compact type AAS instrument in the world.


Safe operation
Safe and reliable control alarm devices used to ensure over-current protection for hollow cathode lamps, insufficient pressure protection for combustion gas/protection gas, leakage alarm of combustion gas, and over-heating protection for the graphite furnace.

Various accessory for all kinds of experiments
Available accessories include a hydride generator, an auto sampler, and a nitrous oxide acetylene gas system, all of which help to further expand the range of applications the AA-7020 is suitable for.

Well-designed mechanism
Enhanced auxiliary gas functionality, all-titanium constructed burner head with automated height adjustment, and automatic liquid trap protection.


Metallurgy, petrochemical, geology, medicine, the environment, scientific research, agriculture (soil), medicines, food, materials science, commodity inspection, and other applications. AA-7020 can analyze up to 70 species in trace element analysis and trace amounts, AA-7020 can be the major instrument in your lab.
