Fast and simple method using DLLME and FAAS for the determination of trace cadmium in honey
TL;DR: In this article, a method for the determination of trace cadmium in honey is presented, which consists of a preconcentration step based on dispersive liquid-liquid microextraction (DLLME) and measurement by flame AAS.

TL;DR: An automatic programmable-flow system capitalizing upon mesofluidic Lab-On-Valve (LOV) sample processing coupled on-line to inductively coupled plasma atomic emission spectrometry (ICP-AES) is proposed in this article for expedient assessment of potential contamination episodes of food safety elements (namely, Cd and Pb) in a variety of undigested ripened honeys, taken as a model of an edible matrix.
Determination of insolubles in diesel lubricating oil by FIA-visible spectrometry.
Moisés Knochen,Alexandra Sixto,Gustavo Pignalosa,S Domenech,Salvador Garrigues,M. de la Guardia +5 more
TL;DR: The proposed method employs visible spectrophotometric detection in association with flow injection analysis for insolubles determination and no evidence of a difference was found between both methods.

Zinc determination in Tannat wine by direct injection onto graphite tube: Electrothermal AAS as an alternative to flame AAS
TL;DR: In this paper, a novel method was developed for the determination of zinc in wine by direct-injection electrothermal atomic absorption spectrometry (ETAAS), which does not require any sample preparation.

Multi-pumping flow system for the determination of boron in eye drops, drinking water and ocean water.
TL;DR: A novel automated method based on the use of pulsed flows that exploits the reaction of azomethine-H in the presence of boron to determination of this element in samples of tap water, ocean water and eye drops was developed and applied.
