Evaluation of quartz tubes as atomization cells for gold determination by thermospray flame furnace atomic absorption spectrometry
(Pergamon-Elsevier Science Ltd, 2012-11)
This work describes the development of a new analytical procedure able to determine gold by thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) using nickel tubes (NiT) and quartz tubes (QT) as atomization ...
Electrothermal metallic furnace atomic absorption spectrometry
(Royal Society of Chemistry, 2017-02)
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 ...

Determination of As(III) in nonacidified groundwater samples for inorganic speciation analysis using flow injection hydride generation atomic absorption spectrometry
(Taylor, 2010-08)
A flow injection system coupled to hydride generation atomic absorption spectrometry with heated quartz tube atomizer was employed for the selective determination of As(III) in real groundwater samples under nonacidic ...
Determination of Tellurium by Electrothermal Atomic Absorption Spectrometry with Preconcentration by Co-Precipitation with Lanthanum Hydroxide
(Atomic Spectroscopy Press Limited, 2005-12)
A procedure for the determination of traces of total tellurium is described which combines electrothermal atomic absorption spectrometry (ETAAS) with preconcentration of the analyte by coprecipitation. The samples, each ...
Selenium analysis by an integrated microwave digestion-needle trap device with hydride sorption on carbon nanotubes and electrothermal atomic absorption spectrometry determination
(Pergamon-Elsevier Science Ltd, 2018-02-04)
An integrated microwave assisted digestion (MW-AD) – needle trap device (NTD) for selenium determination in grape pomace samples is presented. The NTD was filled with oxidized multiwall carbon nanotubes (oxMWCNTS) where ...
Antimony speciation analysis by hydride trapping on hybrid nanoparticles packed in a needle trap device with electro-thermal atomic absorption spectrometry determination
(Royal Society of Chemistry, 2018-12)
Oxidized multiwall carbon nanotubes (oxMWCNTs) were combined with TiO2 nanoparticles to obtain hybrid nanoparticles (HNPs). A miniaturized flow injection (FI) system was introduced for antimony speciation and a headspace ...
