In recent years, the evolution of instrumental techniques such as inductively coupled plasma
(ICP)-based techniques has allowed multielemental analytical capability at trace levels and …

The determination of trace elements in edible oils and biodiesel using atomic spectrometric
methods is reviewed. Problems related to sample pretreatment for appropriate sample …

A new method for the decomposition of soybean based edible products (soy extract, textured
soy protein, transgenic soybeans, and whole soy flour) was developed to essential (Co, Cr …

Advancements in sample preparation for performing trace analysis of inorganic analytes are
coming from the dissemination of microwave-assisted procedures, but there is still room for …

Sample preparation aims to convert analytes to a more suitably detectable form, to separate
them from the sample matrix or to concentrate species for trace analysis. Classical …

In this work, microwave-assisted digestion using the diluted nitric acid procedure for trace
elements determination in rice samples by inductively coupled plasma optical emission …

Many efforts have been made in order to reduce the amount of reagents and waste
produced in analytical laboratories. However, suitable digestion efficiency must be …

Sample preparation has a long history when thinking about the conversion of solid samples
to representative solutions using concentrated acid solutions and high temperature …

The feasibility of diluted nitric acid solutions for microwave-assisted decomposition of
botanical samples in closed vessels was evaluated. Oxygen pressurized atmosphere was …

A green and very fast method for digestion of biological marine samples in choline chloride–
oxalic acid deep eutectic solvent under microwave radiation was developed. These samples …
