AA-7090 Atomic Absorption Spectrophotometer features an 8-lamp auto-turret for rapid elemental lamp selection, enabling true sequential multi-element analysis within a single run. Equipped with an original imported transversely heated graphite furnace and dual background correction modes (longitudinal AC Zeeman and deuterium lamp), it meets diverse analytical requirements.
8-Lamp Auto Turret: Enables rapid automatic lamp selection and true sequential multi-element measurement within a single project.
Wavelength Range: 190–900 nm, with computer-controlled fast automatic wavelength scanning.
Wavelength Range: 190–900 nm, with computer-controlled fast automatic wavelength scanning.
Original Imported Transverse-Heated Graphite Furnace: Features dual background correction modes (longitudinal AC Zeeman and deuterium lamp) to meet diverse analytical requirements.
Burner Head: 10 cm path length, fully constructed of titanium for high salt tolerance and corrosion resistance.
AC Zeeman Background Correction: Adjustable magnetic field strength (0.6–1.1 T) to minimize sensitivity loss caused by line reversal.
Heating Rate: Adjustable up to 2500 °C/s.
Graphite Furnace Viewing System: Facilitates syringe positioning, real-time sample observation, and optimization of furnace temperature programs.
Gas-Saving Mode: Improves protective gas utilization efficiency, extends gas supply duration, and reduces operating costs.
Software-Controlled Functions: Element lamp selection; Wavelength and slit adjustment ; Burner height and gas flow setting; Automatic ignition; Atomizer switching ; Deuterium lamp optical path selection.
Deuterium Lamp Fine-Tuning Mechanism: Ensures precise alignment of deuterium and elemental lamp beams.
