Standard dilution analysis of beverages by microwave-induced plasma optical emission spectrometry
(2016-02-25)
In this work, standard dilution analysis (SDA) is combined with microwave-induced plasma optical emission spectrometry (MIP OES) to determine seven elements in coffee, green tea, energy drink, beer, whiskey and cachaça ...
An eco-friendly infrared method for rapid soil sample preparation for multielemental determination by microwave induced plasma atomic emission spectrometry
(Elsevier Science, 2020-12)
In order to attain Sustainable Development Goals (SDGs), soils mineral assessment is of great importance, since even small changes in their concentration levels, either due to natural or anthropogenic factors, can affect ...
Characteristics of a resonant iris microwave-induced nitrogen plasma
(2016-05-01)
In this work, we use the Boltzmann plot, Saha's equation and the Mg II/Mg I signal ratio to determine temperature (T), electron number density (ne) and robustness of different regions of a microwave-induced nitrogen plasma. ...
Infrared assisted digestion used as a simple green sample preparation method for nutrient analysis of animal feed by microwave induced plasma atomic emission spectrometry
(Elsevier Science, 2021-08)
Based on green analytical chemistry principles it is important to evolve procedures that convert solid samples into solutions without using excessive reagent quantities, energy, temperature, and avoiding waste generation. ...

A green single-tube sample preparation method for wear metal determination in lubricating oil by microwave induced plasma with optical emission spectrometry
(Elsevier Science, 2019-04)
A straightforward and rapid single-tube sample pretreatment for wear metals determination in used lubricating oils was developed in this work as an alternative to the reference pretreatment method (ASTM). A D-optimal mixture ...
Seleção de padrões internos para análise elementar em métodos instrumentais com plasma induzido
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2023-03-08)
This thesis approaches the challenges and strategies to use the internal standardization calibration method in two instrumental methods, i.e. inductively coupled plasma optical emission spectrometry (ICP-OES) and microwave ...
Application of Mixture Design and Kohonen Neural Network for Determination of Macro- and Microelement in Mullet (Mugil cephalus) by MIP OES
(Springer, 2021-01-19)
In this study, the concentrations of macro- and microelement in different tissues (liver, gill, and muscle) of fish collected (Mugil cephalus) in Pontal Bay (Ilheus, Bahia) were determined. A simplex-centroid mixture design ...
