Journal ArticleDOI
Microwave-induced combustion method for the determination of trace and ultratrace element impurities in graphite samples by ICP-OES and ICP-MS
Sandra M. Cruz,Lucas Schmidt,Flávia Michelon Dalla Nora,Matheus F. Pedrotti,Cezar A. Bizzi,Juliano Smanioto Barin,Erico M.M. Flores +6 more
TL;DR: In this paper, a microwave-induced combustion is proposed for graphite digestion and further determination of Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Sr, V and Zn.
Journal ArticleDOI
The synergic effect of microwave and ultraviolet radiation for chocolate digestion and further determination of As, Cd, Ni and Pb by ICP-MS
Carla A. Hartwig,Rodrigo Mendes Pereira,Filipe Soares Rondan,Sandra M. Cruz,Fabio A. Duarte,Erico M.M. Flores,Marcia F. Mesko +6 more
TL;DR: In this article, the synergic effect between microwave and ultraviolet radiation was proposed for chocolate digestion and further toxic element determination by inductively coupled plasma mass spectrometry (ICP-MS).
Journal ArticleDOI
Determination of halogens and sulfur in high-purity polyimide by IC after digestion by MIC.
Sindy R. Krzyzaniak,Rafael F. Santos,Flávia Michelon Dalla Nora,Sandra M. Cruz,Erico M.M. Flores,Paola A. Mello +5 more
TL;DR: Taking into account the lack of methods and the difficulty of bringing this material into solution, MIC can be considered as a suitable alternative for the decomposition of polyimide for routine quality control of halogens and sulfur using IC or ICP-MS.
Journal ArticleDOI
Combining pyrohydrolysis and ICP-MS for bromine and iodine determination in airborne particulate matter
Rochele S. Picoloto,Sandra M. Cruz,Paola A. Mello,Edson I. Muller,Patricia Smichowski,Erico M.M. Flores +5 more
TL;DR: In this paper, a method based on pyrohydrolysis of airborne particulate matter (APM) collected on glass fiber filter and subsequent determination of bromine and iodine by inductively coupled plasma mass spectrometry (ICP-MS) was developed.
Journal ArticleDOI
Determination of rare earth elements in graphite by solid sampling electrothermal vaporization-inductively coupled plasma mass spectrometry
Paola A. Mello,Matheus F. Pedrotti,Sandra M. Cruz,Edson I. Muller,V. L. Dressler,Erico M.M. Flores +5 more
TL;DR: In this paper, a method for the determination of trace rare earth elements (REEs) in graphite by solid sampling electrothermal vaporization-inductively coupled mass spectrometry (ETV-ICP-MS) was proposed.
