Special Issue Information
Dear Colleagues,
Food and environmental samples are characteristic examples of highly complex matrices. For cases such as these, extraction techniques and cleanup strategies are of paramount importance in order to develop accurate and analytical methods with reduced matrix effects. Sometimes the concentration of analytes/pollutants in food and environmental products is lower than the limits of detection and quantification of some analytical instruments. Consequently, there is a need for pre-concentration prior to instrumental analysis. Sample preparation, with the main objective of removal of matrix interferences and preconcentration of the analytes, is considered a bottleneck of analytical processes. Various sample preparation strategies, as applied to food and environmental samples, have been developed based on exhaustive or non-exhaustive extraction of analytes from matrices. Increased interest in sample preparation research has been generated by the introduction of non-traditional extraction technologies. These modern technologies address the need for automation and miniaturization. Current research continues to refine and expand modern extraction methods, integrating novel sorbents, improved cleanup strategies, and innovative solvent systems to enhance sensitivity, selectivity, and matrix compatibility. Examples of the modern extraction techniques used to pre-concentrate analytes/pollutants in food and environmental samples include dispersive solid-phase extraction (DSPE), QuEChERS, dispersive liquid–liquid micro-extraction (DLLME), solid-phase micro-extraction (SPME), thin film micro-extraction (TFME), and solvent bar micro-extraction (SBME). This Special Issue welcomes contributions (high-quality original and critical review papers) focused on experimental studies and theoretical analyses of phenomena associated with and arising from the extraction and removal of analytes/pollutants from both food and environmental samples.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
