Resumo

WITH TUNGSTEN COIL.A CRITICAL RE-VIEW.In this review it is presented some aspects of electrothermal atomic absorption spectrometry with tungsten coil (ETAW-AAS) since its beginning until the present days as well as the perspectives for this technique.Some aspects concerning its development and theoretical concepts are discussed.The analytical figures of merit such as limit of detection (LD), characteristic mass (m 0 ), relative standard deviation (RSD), accuracy and precision are evaluated, compared and discussed considering published works.It is also evaluated its advantages, applications, limitations and instrumental development.The use of diode laser as radiation source and its perspectives to ETAW are also discussed.
