Special Issue Information
Dear Colleagues,
Elemental speciation analysis plays a significant role in modern analytical chemistry. It is known that various elements occur in several chemical forms, called “element species”, in which the toxicity is significantly different. Moreover, the greatest obstacle to determine these forms efficiently is the ease of converting them from one form to another. This significantly influences the risk assessment and provides important data on the processes taking place in the environment. All the above is the challenge for a modern researcher who must deliver new tools in accordance with latest law regulations and environmental requirements. Designing a new analytical instrumentation, e.g., hyphenated techniques, is not enough for speciation studies. Nowadays, proper sample preparation procedures are also required. Firstly, it is desirable to keep the extracted species of the elements unchanged. Secondly, the mutual ratios of the forms must correspond to those in a real sample matrix. Additional advantages are undoubtedly reducing the pretreatment stages, avoiding toxic reagents, limiting the number of extractants used, and lowering their volumes. In the terms of instrumentation, the proposed systems must be able to efficiently separate and determine as many elements as possible in the one run. After optimization and validation of these methods, the applicability must be tested on several sample matrix types. Considering all the above, this Special Issue is addressed to scientists working on the development of advanced analytical methods designed for elemental speciation studies. The main topics cover (1) new procedures of sample preparation; (2) the latest analytical instrumentation with improvement in operating parameters; (3) optimization and validation in multi-elemental speciation analysis; (4) recognition of new element species; and (5) application for several sample matrix types.

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.
