AAS - Atomic Absorption Spectrometer QualiAAS™ Series

Atomic Absorption Spectrophotometry (AAS) quantifies elemental concentrations by measuring the absorption of characteristic wavelengths of light by free, ground-state atoms in a gaseous form. When light from a hollow cathode lamp at the element's specific resonance wavelength passes through an atomized sample, atoms absorb energy in direct proportion to their concentration. That absorption signal, processed through a high-resolution monochromator and photomultiplier tube detector, yields quantitative elemental data with detection limits ranging from parts-per-million (ppm) in flame mode to parts-per-trillion (ppt) in graphite furnace mode. AAS is one of the most selective, sensitive, and cost-accessible elemental analysis techniques available, capable of quantifying over 70 metallic and non-metallic elements from a single integrated platform.

Qualitest's QualiAAS™ Series delivers this analytical power in three fully automatic models engineered for modern laboratory demands. The QualiAAS™ 3000F serves laboratories requiring reliable, high-throughput flame analysis across geology, petrochemistry, food safety, and environmental testing. The QualiAAS™ 3000FG adds fully automatic flame-to-graphite furnace switching, a 70-tray graphite autosampler, and a comprehensive audit trail system — ideal for pharmaceutical quality control, environmental regulatory compliance, and third-party testing. The flagship QualiAAS™ 3000FG-Pro extends this with up to eight simultaneously preheating lamps, native hydride generation for As, Se, Hg, Sb, and Bi, and full electronic signature and user permission management meeting FDA 21 CFR Part 11 requirements. All three models share an identical optical platform: a Czerny-Turner monochromator with 277 mm focal length, 1800 grooves/mm diffraction grating blazed at 250 nm, automatically adjustable spectral bandwidth (0.1–1.6 nm), and an imported high-sensitivity photomultiplier tube detector — delivering a copper flame LOD of ≤0.002 μg/mL and graphite cadmium LOD of ≤0.4 pg across the board.
