Application of atmospheric pressure dielectric barrier discharge plasma for the determination of Se, Sb and Sn with atomic absorption spectrometry

Dielectric barrier discharge plasma atomizer for hydride generation atomic absorption spectrometry—Performance evaluation for selenium

“…Quartz tube atomizers in AAS and diffusion flames in AFS [22,23] are the most common atomizers of hydrides in analytical spectrometry. In the last decade, DBD atomizers have been investigated as alternative hydride atomizers by a couple of authors in both AAS [24][25][26] and AFS [27][28][29][30]. The fundamental drawback of all the present DBD works is, with the exception of our study focused on bismuth hydride atomization in DBD with AAS detection [26], that they include only optimization of the basic DBD parameters followed by analytical figures of merit quantified for the DBD atomizers.…”

“…Selenium hydride was determined by both HG-AAS and HG-AFS with atomization in a DBD atomizer, reaching detection limits of 0.6 ng ml −1 Se for AAS detection [25] and 0.08 ng ml −1 Se for AFS detection [29], respectively. Interestingly, significant difference in detection limits (LOD) reached by HG-DBD-AAS was reported depending on analyte [25], which might indicate significant difference in atomization efficiencies of individual hydrides in the DBD.…”

“…Interestingly, significant difference in detection limits (LOD) reached by HG-DBD-AAS was reported depending on analyte [25], which might indicate significant difference in atomization efficiencies of individual hydrides in the DBD. Whereas LOD of 0.6 ng ml −1 Se was reported, those for Sb and Sn were approximately 20 times higher, reaching 13.0 ng ml −1 Sb and 10.6 ng ml −1 Sn, respectively [25].…”

Determination of Se, Pb, and Sb by atomic fluorescence spectrometry using a new flameless, dielectric barrier discharge atomizer

“…Niemax and coworkers [27,28] have explored a low pressure DBD in conjunction with diode laser atomic absorption spectrometry for the decomposition of chlorofluocarbons and detection of Cl and F. The DBD has also been investigated as a detector for gas chromatography by Gras et al [30]. In our previous studies [31,32], a low temperature atomizer for AAS, based on the DBD, was proposed for hydride-forming elements detection. The results showed that DBD-AAS is a sensitive detector for As, Se, Sb and Sn.…”

Evaluation of a hydride generation-atomic fluorescence system for the determination of arsenic using a dielectric barrier discharge atomizer

“…The use of a DBD in analytical spectrometry have been reported in recent years [33][34][35]. In previous studies [36,37], a low temperature atomizer for atomic absorption spectrometry (AAS), based on the DBD, has been proposed for the determination of hydride-forming elements. However, this atomizer, designed for AAS, cannot be used in the AFS because of the different optical arrangement characteristics of each of these techniques.…”
