An electrothermal atomizer is here narrowly defined as 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) (See Note 1) and
electrothermal atomic fluorescence spectrometry (ETAFS), being defined.
