Atomic Absorption Spectrometers - AAS

Atomic Absorption Spectrometers or AAS measures the concentration of gas phase atoms present in a sample. Solid samples are dissolved and liquid samples often diluted and the resultant liquid samples vaporized in a flame or graphite furnace. As the atoms are vaporized they absorb UV light and the amount of light absorbed is used to determine their concentration.
