The AELAB AA-7020 Series Atomic Absorption Spectrometer provides dual flame and graphite furnace functionality within a compact, fully integrated analytical system. It is engineered for high-precision metal element determination in metallurgy, petrochemical, environmental, and food science laboratories. The instrument ensures excellent optical stability and trace-level detection for over 70 elements.
The AA-7020 Series features a C-T grating optical system with an 1800 lines/mm diffraction grating, automatic bandwidth switching, and Titanium burners. The frame integrates both flame and graphite furnace assemblies, with independent power control and safety protection. The housing is fabricated from corrosion-resistant alloy materials, ensuring long-term stability under demanding laboratory conditions.
The instrument operates on the atomic absorption principle using both flame and electrothermal atomization. The flame system supports air-acetylene and nitrous oxide operation, while the graphite furnace method achieves atomization temperatures up to 3000 °C. Dual background correction—Deuterium lamp and self-absorption—is applied for accurate trace metal quantification. The optical layout ensures repeatable wavelength calibration and superior baseline stability.
The AELAB AA-7020 includes Ethernet and computer connectivity for data communication, with support for PC workstation software, calibration storage, and result printing. USB and optional printer interfaces are available for GLP-compliant reporting and data archiving.
