Tungsten 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 کاملTungsten coil atomic emission spectrometry: calcium determination in biodiesel samples
In this application note, tungsten coil atomic emission spectrometry was used for direct determination of Ca in biodiesel samples. Discrete volumes of biodiesel (10 μL) were directly placed on the tungsten coil with a micropipette and an appropriated heating program was applied to decompose the samples. The first four heating steps (0.32; 0.35; 0.36 and 0.37 V for 20; 50; 50 and 50 s, respectiv...
متن کاملDetermination of dysprosium and europium in sheep faeces by graphite furnace and tungsten coil electrothermal atomic absorption spectrometry.
Tungsten coil atomizer atomic absorption spectrometry (TCAAS) was used to determine Dy and Eu in acid-digested faeces of sheep. These elements were used as markers in animal nutrition studies. Samples were dried, ground and decomposed using a nitric-perchloric acid mixture. The accuracy of the developed method was evaluated by graphite furnace atomic absorption spectrometry (GFAAS). The results...
متن کاملTungsten coil atomic emission spectrometry combined with dispersive liquid-liquid microextraction: A synergistic association for chromium determination in water samples.
A novel and environment friendly analytical method is reported for total chromium determination and chromium speciation in water samples, whereby tungsten coil atomic emission spectrometry (WCAES) is combined with in situ ionic liquid formation dispersive liquid-liquid microextraction (in situ IL-DLLME). A two stage multivariate optimization approach has been developed employing a Plackett-Burm...
متن کاملCaesium and lanthanum suppression of signal fluctuation in flame atomic absorption and atomic emission spectrometry.
This article describes the concept of controlling and correcting interference resulting from flame instability and sample reduction in absorption atomic spectrometry with flame atomization. Using popular laboratory spectrometers, which enable simultaneous or fast sequential measurements of many elements in the course of a single analysis, methods of controlling and correcting problems with inst...
