Special Issue Information
Dear Colleagues,
Sample preparation has long been recognized as the bottleneck in the analytical process, estimated to account for 70% of the overall chemical analysis. Errors introduced during this phase of chemical analysis can irreparably compromise the results. The scientific community has continually sought to improve sample preparation by developing increasingly advanced techniques aimed at maximizing recovery and eliminating interferences that could adversely impact the analysis. Currently, sample preparation techniques can be categorized into three categories: sorbent-based techniques, organic solvent-based techniques, and techniques based on the use of supercritical or subcritical fluids. In the past decade, the miniaturization of these techniques has gained significant attention from the scientific community, along with the development of nanocomposite materials and next-generation solvents. Sample preparation techniques are frequently coupled with instrumental methodologies for the determination and quantitation of analytes, such as high-performance liquid chromatography (HPLC) or gas chromatography (GC), both of which can be paired with standard detectors or mass spectrometry (MS). This Special Issue aims to highlight sample preparation techniques that can be effectively applied in the extraction or micro-extraction of analytes from various matrices and their determination through instrumental methods or sensor-based approaches.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Molecules is an international peer-reviewed open access semimonthly 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 2700 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.
