GF-AAS (Graphite Furnace Atomic Absorption Spectrometry), also known as graphite furnace atomic absorption spectrometry, is an analytical technique developed by Jena Analytik. This technique is used to determine the concentrations of various metals in a sample.
In GF-AAS, the sample is vaporized and atomized in a graphite tube. Light of a specific wavelength is then passed through the sample. The atoms of the metals absorb light at characteristic wavelengths and the absorption is measured. By measuring the absorption at these specific wavelengths, the concentration of the metals in the sample can be determined.
GF-AAS is an extremely sensitive elemental analysis technique and is well suited for the determination of trace metals in a wide variety of samples, including environmental samples, plastics, electronic components and pharmaceuticals. It can also be used for matrix analysis for material determination.
