Atomic Absorption Spectrometers - AAS

Atomic Absorption Spectrometers use particular wavelengths of light to evaluate the concentration of gas-phase atoms in a liquid or solid sample. After a solid sample is dissolved in a liquid or a liquid sample is diluted, the resulting sample is tested. First by being vaporized with a flame or graphite furnace, and light is then passed through the vaporized sample and a detector then assesses any shifts in the wavelength of light. Atomic Absorption Spectrometers are commonly used to find trace metals in natural bodies of water, municipal water supplies, pharmaceuticals, foods, geological specimens, petroleum products, biological specimens and forensic samples. It is typical to get outcomes on the scale of parts-per-million (ppm). A greater sensitivity of parts-per-billion (ppb) is common in some applications.
