Determination of traces of sulphur by electrothermal evaporation and non-thermal excitation of S-containing species in a hollow cathode discharge (FANES/MONES) and in a microwave induced plasma (MIP)

Tungsten Coil Devices in Atomic Spectrometry: Absorption, Fluorescence, and Emission

“…In addition, the purge gas also acts as a coolant for the device, so no water circulating system is required. The use of W-Coils in analytical atomic spectrometry dates back to the early 1970s, when they were used as atomizers for electrothermal atomization atomic absorption spectrometry (ETAAS) by Piepmeier et al 1,2 and for electrothermal atomization atomic fluorescence spectrometry (ETAFS) by Winefordner et al 3 Since then, W-Coils have been used in virtually all areas of atomic spectrometry: as atomizers for ETAAS and ETAFS, as ETV devices for inductively coupled plasmas (ICPs) or microwave induced plasmas (MIPs) atomic emission spectrometry (AES) [4][5][6] and mass spectrometry (MS). 7 Early on, however, W-Coils did not find widespread acceptance, perhaps due to the tremendous technical and commercial success of graphite furnace ETAAS instrumentation.…”

Determination of Sulfur in Grape and Apricot Samples Using High-resolution Continuum Source Electrothermal Molecular Absorption Spectrometry

“…There were several absorption lines, which were reported to be the most sensitive lines (257.593; 257.958; 258.056) for sulfur determination. 27 Dittrich et al 28 determined sulfur at 469.413 nm using the normal atmospheric argon-a microwave-induced plasma method, and at 383.73 nm (S2 molecular band) using a glow discharge in the furnace nonthermal excitation spectrometry/molecular nonthermal excitation spectrometry method based on the emissions of S atoms, S + ions, S2 and CS molecules using sulfate.…”

Atomic absorption, atomic emission, and flame emission spectrometry

“…For the determination of P, FANES gave a much lower detection limit than ETAAS (292). Molecular nonthermal excitation spectrometry (MONES) was used for the determination of P (293) and S (294). Dittrich et al ( 295) developed an interesting hybrid technique, laser-FANES, for the analysis of solid samples.…”
