electrothermal atomizer

An electrothermal atomizer is a device which is heated, to the temperature required for analyte atomization, by the passage of electrical current through its body. This technique has largely been developed for use in atomic absorption spectrometry for which the terms electrothermal atomic absorption spectrometry, electrothermal AAS and the abbreviation ETAAS are defined. It has also been applied in atomic emission and atomic fluorescence spectrometry, with appropriate analogous terms, such as electrothermal atomic emission spectrometry (ETAES) and electrothermal atomic fluorescence spectrometry (ETAFS), being defined.
