High-resolution continuum source electrothermal atomic absorption spectrometry — An analytical and diagnostic tool for trace analysis

Determination of Ca, Cd, Cu, Fe, K, Mg, Mn, Mo, Na, Se, and Zn in Foodstuffs by Atomic Spectrometry After Sample Preparation Using a Low-Cost Closed-Vessel Conductively Heated Digestion System

“…Comparing to conventional LS FAAS, possibilities of background correction and elimination of interferences are increased because the spectral environment of the analytical line can be completely explored. The greatest advantage of HR-CS FAAS in relation to LS FAAS is the need for only one single lamp for all elements instead of one lamp for each element (Welz et al 2003(Welz et al , 2007Becker-Ross et al 2006;Villanueva-Alonso et al 2009). In the recent years, it was demonstrated in literature a great interest in applying HR-CS FAAS to determine various analytes in food samples (Paz-Rodríguez et al 2015;Ozbek and Baysal 2015;Li and Chen 2014;Brandao et al 2010Brandao et al , 2011.…”

Liquid-phase microextraction combined with graphite furnace atomic absorption spectrometry: A review

“…To sum up, HR-CS-GFAAS seems to be a more flexible technique than the classic instrumentation with better limits of detection, significantly better background and spectral interferences correction system than conventional GFAAS. Several reviews focused on HR-CS-GFAAS are available in the literature for interesting readers [145][146][147][148][149].The combination of LPME-HR-CS-GFAAS has been performed in few recent publications. Concretely, they involved the preconcentration of Cd from vegetable oils by UA-SDME [37], Cr from effluents and water sources by DLLME-SFO [67] and Pt from geological samples and spent automobile converter by DSDME [150] prior to HR-CS-GFAAS.…”

Caesium and Lanthanum Suppression of Signal Fluctuation in Flame Atomic Absorption and Atomic Emission Spectrometry

“…2,3 Several solutions were suggested, such as use of continuous radiation sources and, eventually, use of multi-channel devices, which are in use to this day. [4][5][6][7][8][9][10] The solutions of multi-element determination in atomic absorption have been used in connection with the generation of volatile hydrides (hydride generation atomic absorption spectrometry: HGAAS) 11 , flame (flame atomic absorption spectrometry: FAAS) 12 or electrothermal atomisation mode (electrothermal atomic absorption spectrometry: ETAAS). [13][14][15] The flame atomic absorption spectrometry techniques also enable rapid sequential determination of elements whose resonance lines are in close proximity to one another.…”
