Special Issue Information
Dear Colleagues,
Analytical pyrolysis–gas chromatography–mass spectrometry (Py-GC-MS) is a laboratory procedure in which small amounts of high-molecular organic materials, such as synthetic polymers or biopolymers, undergo thermal treatment and separations. This technology deals with the structural identification and quantitation of pyrolysis products with the ultimate aim of establishing the identity of the original material and its thermal decomposition mechanisms. Pyrolysis temperatures of 550–1400°C are high enough to break molecular bonds in macromolecules, thereby forming smaller, simpler volatile compounds. The pyrolytic process is carried out in a pyrolyzer interfaced with analytical instrumentation, such as gas chromatography (GC), mass spectrometry (MS), and gas chromatography coupled with mass spectrometry (GC-MS) or with Fourier transform infrared spectroscopy (GC-FTIR). Via a measurement and identification of pyrolysis products, the molecular composition of the original sample can often be reconstructed. Applications of Py-GC-MS range from research and development of new materials, characterization and competitor product evaluation, medicine, biology and biotechnology, geology, airspace, and environmental analysis (microplastics and nanoplastics) to forensic purposes or conservation and the restoration of cultural heritage. These applications cover the analysis and identification of synthetic polymers/copolymers and biopolymers. Analytical pyrolysis–gas chromatography–mass spectrometry allows the confirmation of a failed product’s source, the identification of contaminants causing failure, competitive analysis, and allows us to overcome problems in product development or quality control. This technique is often used for wood studies due to its ability to provide details of the lignocellulose’s molecular structure.
We are pleased to invite you to contribute to this Special Issue of Separations on the analytical pyrolysis–gas chromatography–mass spectrometry of synthetic polymers/copolymers and biopolymers, which will be focused on the new developments and applications in this hyphenated technique.
In this Special Issue, case reports, original research articles, and reviews are particularly welcome.
I look forward to receiving your contributions.

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. 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.
