Journal ArticleDOI
Detection of the origin of Brazilian wines based on the determination of only four elements using high-resolution continuum source flame AAS.
Wiliam Boschetti,Roger T. Rampazzo,Morgana B. Dessuy,Morgana B. Dessuy,Maria Goreti R. Vale,Maria Goreti R. Vale,Alessandro de Oliveira Rios,Plinho Francisco Hertz,Vitor Manfroi,Paulo Gustavo Celso,Marco Flôres Ferrão +10 more
TL;DR: A method has been developed to determine 10 elements in Brazilian red wines using high-resolution continuum source flame atomic absorption spectrometry, a technique that allows the fast sequential determination of an essentially unlimited number of elements per sample.
Journal ArticleDOI
Comparison of direct solid sampling and slurry sampling for the determination of cadmium in wheat flour by electrothermal atomic absorption spectrometry
Rennan Geovanny Oliveira Araujo,Nédio Oleszczuk,Roger T. Rampazzo,Pedro de Almeida Costa,Márcia M. Silva,Maria Goreti R. Vale,Bernhard Welz,Sergio Luis Costa Ferreira +7 more
TL;DR: Two analytical methods for the determination of cadmium in wheat flour by electrothermal atomic absorption spectrometry without prior sample digestion have been compared and direct SS was finally adopted as the method of choice, due to its greater simplicity, the faster speed of analysis and the better figures of merit.
Journal ArticleDOI
Mineral characterization of native fruits from the southern region of Brazil
Marina C. Pereira,Wiliam Boschetti,Roger T. Rampazzo,Paulo Gustavo Celso,Plinho Francisco Hertz,Alessandro de Oliveira Rios,Márcia Vizzotto,Simone Hickmann Flôres +7 more
TL;DR: In this article, the mineral composition and content present in seven native fruit species of Southern Brazil using inductively coupled plasma optical emission spectrometry (ICP-OES) were characterized.
Journal ArticleDOI
Direct determination of arsenic in petroleum derivatives by graphite furnace atomic absorption spectrometry: A comparison between filter and platform atomizers
Emilene M. Becker,Roger T. Rampazzo,Morgana B. Dessuy,Maria Goreti R. Vale,Maria Goreti R. Vale,Márcia M. Silva,Bernhard Welz,Bernhard Welz,D. A. Katskov +8 more
TL;DR: In this article, a direct method for the determination of arsenic in petroleum derivatives has been developed, comparing the performance of a commercial transversely heated platform atomizer (THPA) with that of a Transversely heated filter atomizer(THFA).
Journal ArticleDOI
Method Development and Total Uncertainty Estimation for Boron, Sulfur and Phosphorus Determination in Mineral Fertilizer Using ICP OES
TL;DR: In this paper, the uncertainties of the method were estimated according to the bottom-up approach, which were 7.1, 4.3, and 7.8% for B, S and P, respectively.
