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...
