Green Sample Preparation Techniques
2023There is a trend in analytical chemistry towards development of eco-friendly methods of sample preparation without loss of efficiency. This book provides a general, critical, and updated vision of the different green sample preparation approaches that have been developed. These include miniaturisation of the extraction techniques that allow a reduction

Green Sample Preparation Methods
2011Sample preparation is the stage of the analytical process where greenness-related issues can likely play the most important role. With the exception of direct methods for solid sample analysis, for most analytical methods it is necessary to carry out a certain number of operations to make the sample amenable to the instrument.

Greening sample preparation in inorganic analysis
TrAC Trends in Analytical Chemistry, 2013Sample 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 procedures often yield large amounts of toxic waste, but environment-friendly alternatives can be implemented without impairing the analytical performance. Green methods are also

Molecularly Imprinted Polymers in Green Sample Preparation
2023The use of molecularly imprinted polymers in sample preparation is nowadays well-established thanks to their ability to provide unprecedented selectivity during extraction and clean-up steps. However, both their synthesis and subsequent use are far from being considered green.

Green molecularly imprinted polymers for sustainable sample preparation
Journal of Separation Science, 2021AbstractThe use of molecularly imprinted polymers in sample preparation as selective sorbent materials has received great attention during the last years leading to analytical methods with unprecedented selectivity. However, with the progressive implementation of Green Analytical Chemistry principles, it is necessary to critically review the greenness ...

Supramolecular Solvents (SUPRASs) in Green Sample Preparation
2023Supramolecular solvents (SUPRASs) are water-immiscible nanostructured liquids composed of a 3D network of amphiphilic aggregates that maintain their structures via non-covalent interactions. These solvents are prepared from aquo/organic solutions of amphiphiles at concentrations above their critical aggregation concentration.

Green Sample Preparation Applications for Environmental Analysis
2023Environmental contamination is one of the most significant threats to living beings. The main source of contamination is anthropogenic activity, which generates many wastes with a high impact on ecosystems and human life. The monitoring of these toxic substances in the environment (water, soil, sediments, biota, and air) is of special importance to ...

Green Chemistry Considerations for Sample Preparation
2011Green chemistry is the design, development and implementation of chemical products and processes to reduce or eliminate the use and generation of substances hazardous to both human health and/or the environment. Although advances in instrumentation have been made to reduce the amount of organic solvents needed for analytical testing (e.g., reduced ...

Green Bioanalytical Sample Preparation: Fabric Phase Sorptive Extraction
Bioanalysis, 2021Fabric phase sorptive extraction (FPSE) is a recently introduced sample preparation technique that has attracted substantial interest of the scientific community dealing with bioanalysis. This technique is based on a permeable and flexible substrate made of fabric, coated with a sol-gel organic-inorganic sorbent.

Green approaches in sample preparation of bioanalytical samples prior to chromatographic analysis
Journal of Chromatography B, 2017Sample preparation is considered to be the most challenging step of the analytical procedure, since it has an effect on the whole analytical methodology, therefore it contributes significantly to the greenness or lack of it of the entire process. The elimination of the sample treatment steps, pursuing at the same time the reduction of the amount of the
