Atomic absorption spectrometers

Atomic absorption analysis of metals

AAS instruments determine elemental concentrations through light absorption by free atoms. Applications include water, food raw materials, prepared soil samples and industrial solutions.

Selecting a spectrometer

• Flame atomisation for routine levels or a graphite furnace for lower concentrations.
• Target elements, lamps and turret positions.
• Background correction, working range and sample introduction automation.
• Gas supplies, compressor, extraction and sample preparation.

Hydride-forming elements may require specialised accessories. Lamps and auxiliary equipment depend on the configuration. For another approach to elemental analysis, explore XRF spectrometers.
