Resumen:
We present an atomization system for atomic absorption spectrometry comprised of a stainless steel furnace heated by the Joule effect by means of its intrinsic resistance. This new kind of furnace does not require any gases during operation. Samples are introduced with an independently controlled thermospray injector. Thedevice outperforms conventional FAAS (Flame Atomic Absorption Spectrometry) for many analytes,providing a very safe, compact and inexpensive alternative for many analytical determinations. Full characterization of the system is presented, and theoretical simulations are contrasted with experimental data
