The Role of Green Sample Preparation in Food Chemistry Applications
2023Food analysis is a tricky issue due to the great complexity of matrices. Even if very selective and sensitive analytical techniques are applied, an effective procedure of isolation is a preliminary indispensable step. Over the last few years the attention of the scientific community has been devoted to the development of procedures, materials, and ...

Green solvents for sample preparation in analytical chemistry
Current Opinion in Green and Sustainable Chemistry, 2017An analytical procedure comprises two steps: sample preparation mostly extraction (Soxhlet, Dean–Stark, Likens– Nickerson, Blye & Dyer, Folch, leaching, maceration, percolation) and analysis (spectrophotometry, chromatography, spectrometry). Whereas chemical analysis is finished after few minutes, extraction takes at least several hours and requires ...

Evolution and status of preparative gas chromatography as a green sample-preparation technique
TrAC Trends in Analytical Chemistry, 2015Abstract The present paper reviews recent approaches to preparative capillary gas chromatography (PCGC) covering the period 2010–14. The “green” character of this approach is discussed in relation to the capability to collect chemicals from complex samples, avoiding the consumption of organic solvents that represent a great environmental issue.

Green Sample Preparations for the Bioanalysis of Drugs of Abuse in Complex Matrices
Bioanalysis, 2019The sample preparation is the most critical step involved in the bioanalytical process. When dealing with green analytical chemistry, sample preparation can be even more challenging. To fit the green analytical chemistry principles, efforts should be made toward the elimination or reduction of the use of toxic reagents and solvents, minimization of ...

“Green” nature of the process of derivatization in analytical sample preparation
TrAC Trends in Analytical Chemistry, 2018Abstract Nowadays, the idea of Green Analytical Chemistry (GAC) is of high importance what impacts on the rapid growth in the sample preparation area with special emphasis on sample preparation simplification, miniaturization, and automation. Because the derivatization process is often an essential element of the analytical procedure, it should be ...

Electrophoretic concentration — a simple and green approach for sample preparation
2017Electrophoretic concentration (EC) is an electric field-driven and environmentally friendly off-line sample preparation for charged analytes. EC was demonstrated for the enrichment of either six anionic pollutants or five cationic drugs from purified, drinking, river, or waste- water samples.
