Introduction atomic-absorption (aa) spectroscopy uses the absorption of light to measure the concentration of gas-phase atoms since samples are usually liquids or solids, the analyte atoms or ions must be vaporized in a flame or graphite furnace. Used atomic absorption spectrophotometers, refurbished atomic absorption spectrophotometers (aa), used aa, refurbished aa, used. Whether your single-element inorganic analysis application requires flame furnace or graphite furnace atomic absorption (aa), we offer state-of-the-art, high-performance instrumentation, and support you with more than 50 years of experience as the industry leader in atomic absorption spectroscopy. Atomic-absorption (aa) spectroscopy uses the absorption of light to measure the concentration of gas-phase atoms since samples are usually liquids or solids, the analyte atoms or ions must be vaporized in a flame or graphite furnace.
Atomic absorption (aa) is a scientific testing method used for detecting metals in solution the sample is fragmented into very small drops (atomized) it. The analyte concentration is determined from the amount of absorption 7 - concentration measurements are usually determined from a working curve after. Absorption and emission: in atomic absorption (aa) spectroscopy, absorption of a photon results in excitation of an electron from a lower to higher energy atomic orbital (ao.
