Influence of Atomizer Nature on Precision in Graphite Furnance - Atomic Absorption Spectrometry

Abstract

The graphite nature used for confectioning the graphite furnaces influences considerably the peak shapes. With the use of normal graphite the evolution of the peak is much slower and the shape is also altered. As a consequence the instrument has a better chance to “catch” and measure the peak height and area, this resulting in an overall better precision and accuracy.
