Atomic Absorption Spectrophotometer AA-7090, 0.6-1.1 T Magnetic Field (CAT#: STEM-AL-9631-ZJF)

The AA-7090 is an atomic absorption spectrophotometer for sequential multi-element analysis. An eight-lamp automatic turret selects the required elemental lamp for each measurement sequence. The graphite-furnace configuration uses transverse heating together with longitudinal alternating-field Zeeman and deuterium-lamp background correction. The magnetic field is adjustable from 0.6 to 1.1 T in six steps with 0.1 T increments. A 10 cm titanium burner head is listed for flame measurements. A graphite-furnace viewing system supports positioning of the injection needle and observation of the sample within the graphite tube. Software control covers lamp selection, wavelength selection, slit selection, burner height, gas flow, ignition, atomizer switching, and deuterium-lamp optical switching. A titanium nebulization chamber is used for corrosion-resistant flame-sample introduction.
