TL;DR: The wastes of edible insect breeding should be collected and evaluated as an alternative of chitin/chitosan source and characterized using DSC, FT-IR, XRD, TGA, and SEM techniques demonstrate consistency with the degree of deacetylation of the obtained chitOSan, allowing the differentiation between chit in and chitosans.

TL;DR: In this article, the authors used cold vapor atomic absorption spectrometry (CV-AAS) for the determination of Hg in biological samples by using a simple and inexpensive system for sample digestion.

TL;DR: In this article, the authors provided information about the total concentration and bioaccessible fraction of metals Al, Ba, Bi, Ca, Cd, Cr, Cu, Fe, Mn, Pb, Ti and Zn in nine different infant cereal samples.

TL;DR: In this article, a new procedure based on exposure of ethanol biofuel samples to UV radiation in the presence of low molecular weight organic acids was developed for the determination of total Hg (inorganic and organometallic species: Hg2+, CH3Hg+ and CH3CH2Hg+) by photochemical vapor generation coupled with atomic absorption spectrometry (photo-CV-AAS).

TL;DR: In this paper, a comparative study between three acid decomposition procedures of milk powder samples for the determination of Ca, Cu, Fe, K, and Na by optical emission spectrometry with inductively coupled plasma is presented.
