WebMar 9, 2015 · Hot steel-making furnaces lined with carbon-bearing refractory brick can be severely deteriorated in a short period of time when not protected from air. Similarly, carbon or graphite electrodes in electric arc furnaces exposed to air, CO2, or other oxidizing agents while hot will oxidize, which is the principal cause of deterioration. Graphite furnace atomic absorption spectroscopy (GFAAS) (also known as Electrothermal Atomic absorption spectroscopy (ETAAS)) is a type of spectrometry that uses a graphite-coated furnace to vaporize the sample. Briefly, the technique is based on the fact that free atoms will absorb light at frequencies or wavelengths characteristic of the element of interest (hence the name atomic absorption spectrometry). Within certain limits, the amount of light absorbed can be linearly corr…
