GC, MS and GC-MS Analytical Methods: Opportunities and Challenges (Third Edition)

Dear Colleagues,

Gas chromatography (GC) is an analytical technique that has been used to separate volatile components from incredibly complex and varied matrices (smoke, fuel spills, etc.), enabling their subsequent identification and/or quantification. GC has been coupled to multiple detectors, such as mass spectrometers (MSs), which provide significantly high sensitivity (in the ppb range) for the analysis performed and for the exact identification of previously separated components. Recently, some researchers have started to use MSs as chemosensors, in which each fragment ion (m/z ratio) acts as a sensor and its abundance is equivalent to the signal of this sensor, providing the characteristic total profile of each sample, like a fingerprint; this allows the resolution of an analytical problem without the identification of the compounds. This trend has also been observed among other GC-coupled detectors, such as ion mobility spectroscopy or even UV–Vis spectroscopy.

This Special Issue, "GC, MS and GC-MS Analytical Methods: Opportunities and Challenges (Third Edition)", aims to provide a forum for the latest research on the application of gas chromatography and/or mass spectrometry as chemosensors for analytical purposes. Both review articles and research papers are welcome.

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. Chemosensors 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 2000 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.
