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.

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.

TL;DR: In this article, the authors used inductively coupled plasma optical emission spectrometer (ICP-OES) to analyze 12 elements (Al, B, Ba, Ca, Cu, Fe, K, Li, Mg, Mn, Na and Sr) from 111 sparkling wine samples belonging to four countries (41 Brazilian, 42 Argentinean, 11 Spanish and 17 French).

TL;DR: A multivariate-based framework aimed at identifying relevant chemical elements ( features) for classifying sparkling wine samples according to the country of origin is proposed, which obtained average 100% accurate classifications when retaining only 3 of the original features.

TL;DR: In this article , three portable NIR instruments were evaluated to verify the authenticity of almond flours and the results were compared with a bench-top FT-NIR, which achieved 100% sensitivity and more than 95% specificity for samples with adulterant concentration of 5% or above.
