Convenient Modifications to a Varian AA-6 Atomic Absorption Spectrometer to Allow Use with a Graphite Furnace Atomizer
Abstract:Atomic absorption spectroscopy (AAS) has become a popular and routine technique for trace metal analysis over the past 25 years. One of the most significant advances to occur during this period was the development of the graphite furnace atomizer. This atomizer has greatly improved sensitivities and detection limits for AAS, but at the same time has placed greater instrumental demands on the spectrometer electronics than does a flame atomizer. The instrumental demands are due to the nature of the signal. When using a furnace atomizer the signal takes the form of an absorbance pulse or peak as opposed to the static signal observed when using a flame atomizer. Recently, peak shape analysis has been shown to be a valuable tool for investigating matrix interferences when using a graphite furnace atomizer.
