AA-7090 Atomic Absorption Spectrophotometer

The AA-7090 Atomic Absorption Spectrophotometer features an eight-lamp automatic turret for rapid automatic selection of element lamps, enabling true sequential determination of multiple elements in the same project. It is equipped with an imported transverse-heated graphite furnace and adopts both longitudinal AC Zeeman and deuterium lamp background correction modes to meet the analytical needs of different users.

• Eight-lamp automatic turret for rapid automatic selection of element lamps, enabling true sequential determination of multiple elements in the same project;   

• Wavelength range: 190nm~900nm, with computer-controlled automatic fast wavelength scanning;    

• Imported transverse-heated graphite furnace, adopting both longitudinal AC Zeeman and deuterium lamp background correction modes to meet the analytical needs of different users;
