Evaluation of a Continuum Source Tungsten Coil Atomic Absorption Spectrometer: A Study of Zn Behavior
نویسندگان
چکیده
O desempenho de um espectrômetro de absorção atômica com filamento de tungstênio, fonte contínua de deutério, monocromador Czerny-Turner e um detector de estado sólido foi avaliado para Zn. As principais características do instrumento são a simplicidade de operação e o custo relativamente baixo. Apesar do alto limite de detecção (40 μg L, 3 desvio padrão do branco/coeficiente angular), Zn foi determinado com exatidão em uma amostra de água e uma amostra de urina certificadas. A recuperação em água foi de 106% e em urina o resultado obtido está na região aceitável do certificado.

Analytical characteristics of a continuum-source tungsten coil atomic absorption spectrometer.
A continuum-source tungsten coil electrothermal atomic absorption spectrometer has been assembled, evaluated, and employed in four different applications. The instrument consists of a xenon arc lamp light source, a tungsten coil atomizer, a Czerny-Turner high resolution monochromator, and a linear photodiode array detector. This instrument provides simultaneous multi-element analyses across a 4...
متن کاملFraunhofer effect atomic absorption spectrometry.
The dark lines in the solar spectrum were discovered by Wollaston and cataloged by Fraunhofer in the early days of the 19th century. Some years later, Kirchhoff explained the appearance of the dark lines: the sun was acting as a continuum light source and metals in the ground state in its atmosphere were absorbing characteristic narrow regions of the spectrum. This discovery eventually spawned ...
متن کاملTungsten coil devices in atomic spectrometry: absorption, fluorescence, and emission.
In this work, tungsten coil (W-Coil) devices are used as atomizers for electrothermal atomization atomic absorption spectrometry (ETAAS), electrothermal atomization laser excited atomic fluorescence spectrometry (ETA-LEAFS), and electrothermal vaporization inductively coupled plasma atomic emission spectrometry (ETV-ICP-AES). For most cases in ETAAS and ETA-LEAFS, limits of detection (LODs) usi...
متن کاملA portable tungsten coil atomic emission spectrometer for the simultaneous determination of metals in water and soil samples.
Tungsten coil atomic emission spectrometry (WCAES) has been evaluated as a potentially portable technique for field applications. The tungsten coil (W-coil) was extracted from a commercially available slide projector bulb and used as both the atomizer and the excitation source. The coil was powered by a small solid-state power supply. A hand-held CCD spectrometer, powered from a laptop computer...
متن کاملValidation of an analytical method based on the high-resolution continuum source flame atomic absorption spectrometry for the fast-sequential determination of several hazardous/priority hazardous metals in soil
BACKGROUND The aim of this paper was the validation of a new analytical method based on the high-resolution continuum source flame atomic absorption spectrometry for the fast-sequential determination of several hazardous/priority hazardous metals (Ag, Cd, Co, Cr, Cu, Ni, Pb and Zn) in soil after microwave assisted digestion in aqua regia. Determinations were performed on the ContrAA 300 (Analyt...
