Atomic absorption

Understanding Atomic Absorption Spectroscopy

Atomic absorption spectroscopy (AAS) is widely used for determining the concentration of metallic elements in environmental, clinical, and industrial samples. Typical applications include monitoring heavy metals in water, quality control in pharmaceutical manufacturing, and analysing soil or plant materials in agricultural research. Key components of an atomic absorption spectrometer include the light source (usually hollow cathode lamps), atomiser (flame or graphite furnace), monochromator, and detector.

When selecting an atomic absorption spectrometer, buyers often consider features such as detection limits, sample throughput, types of atomisers compatible with the instrument, and ease of software operation. Terminology you may encounter includes flame AAS, furnace AAS, calibration curves, and spectral lines specific to the metals analysed (e.g., lead, cadmium, copper).

• Principle: measuring light absorption by free atoms to quantify elements
• Common atomisers: air-acetylene flames, graphite furnaces
• Applications: environmental testing, food safety, clinical analysis
• Parameters: sensitivity, precision, matrix compatibility
