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