Development, Validation, and Application of Methods for the Multi-Element Analysis of Samples with Different Matrices Using Spectrometric Techniques

Dear Colleagues,

Elemental characterization of various matrices, such as food, industrial, environmental, or biological samples, using spectrometric techniques, such as ICP OES, ICP MS, FAAS, and ETAAS, arouses a constant research interest, particularly because of the possibility to evaluate the quality and safety of these materials and their suitability for direct applications. Multi-element analysis of samples, especially those of a complex composition, is not an easy task, and causes a permanent necessity to develop and use valid methods that guaranty reliable and dependable results. One of the most important and demanding steps in the analytical process is sample preparation before measurements, depending on the composition of the sample matrix, the type and concentration of analytes, and the detection technique used for the quantification of these analytes. In a traditional approach, samples are decomposed by wet acidic digestion procedures in the presence of concentrated oxidizing acids; however, followed the idea of simplifying the analytical proceeding, alternative methodologies at the stage of sample preparation that fit in with the principles of “green chemistry” are also currently being developed. In view of this, this Special Issue is addressed to all analytical chemists dealing with the determination of major, minor, and trace elements is various samples using spectrometric techniques, with special attention to the development and validation of new methods of element analysis. Scientific areas to be covered by this Special Issue may include (but are not limited to) the following topics:

i) multi-element analysis of samples with different matrices, including food, environmental, industrial, or biological materials;
ii) speciation and/or fractionation of elements;
iii) sample preparation procedures before spectrometric measurements;
iv) method validation, verification, and application.
