WebMar 16, 2024 · Thomas Wenzel. Bates College. The graphite furnace, which is pictured in Figure 6.2 B. 3, is a small, hollow graphite tube about 2 Inches long by ¼ inch in diameter with a hole in the top. Graphite furnaces are used for atomic absorbance measurements. Radiation from the source shines through the tube to the detector. WebWhat are advantages to using a furnace instead of a flame in atomic absorption? a.) the sample is atomized in only one heating step b.) less operator skill is required to determine the proper experimental conditions c.) higher sensitivity because the atomized sample is in the optical path longer d.) a smaller sample amount is required e.) memory effects from …
