Atomic Absorption Spectrophotometer

To measure the concentration of metal ions in a liquid sample

To measure the concentration of molecules in a liquid sample

To analyze the composition of gases

To measure the concentration of organic compounds

Atomic absorption measures the concentration of metal ions, while spectroscopy measures the concentration of molecules

Atomic absorption measures the concentration of molecules, while spectroscopy measures the concentration of metal ions

Atomic absorption uses specific wavelengths of light, while spectroscopy uses a broad range of wavelengths

Atomic absorption uses a flame as the light source, while spectroscopy uses a laser
