This work evaluates the use of an internal standard for acquiring the elemental mapping of ¹⁰⁷Ag, ⁵⁵Mn and ⁶³Cu using laser ablation inductively coupled plasma mass spectrometry in the imaging mode from soybean leaves cultivated in the absence or in the presence of silver nanoparticles (40 nm average size) and also using silver nitrate for comparative purposes.

The results originated from the application of a simple and straightforward photochemical reactor to generate volatile species from noble metals (Au, Ir, Pd, Pt and Rh) are presented.

The risk from potentially toxic elements in airborne particulate matter collected on air filters is assessed using a batch in vitro method.

Accurate determination of Hg in soil/sludge samples by HR-CS GFAAS achieved using AuNPs as a chemical modifier and leaching/slurry as sample preparation.

In this work, a method for the determination of As, Sb, Se and Te in mineral coal was developed using solid sampling electrothermal vaporization inductively coupled plasma mass spectrometry (SS-ETV-ICP-MS).

This work describes an adequate method for the stabilization of three forms of sulfur (ionic, saturated, and unsaturated), with different chemical modifiers (Zr, Pd and Ca) during sulfur measurement as carbon monosulfide (CS) by high-resolution continuum source graphite furnace molecular absorption spectrometry.

In this work, an improved conductively heated digestion system (CHDS) with closed vessels, which provides simpler, easier and safer digestion of raw chicken, beef and pork meat samples aiming at Ca, Cu, Fe, K, Mg, Mn, Na, P, S, and Zn determinations by ICP OES and As, Cd, Cr, Mo, Pb and Se by ICP-MS/MS, was evaluated.

The first report of quantitative measurement of calcium, magnesium, potassium and sodium in bovine and chicken meat by LIBS.

The direct analysis of high silicon content samples by Laser-Induced Breakdown Spectrometry (LIBS) is a good alternative, since the decomposition of samples with refractory characteristics is not an easy task.
