Special Issue Information

Dear Colleagues,

For decades, Volatile Organic Compounds (VOCs) have been of great interest within the worldwide research community. They are organic compounds of natural or anthropogenic origin with very high vapor pressure and low boiling points. Biogenic VOCs are mainly emitted by plants, but they also can be emitted by animals and microorganisms. They are involved in communication between animals and plants. The branch of chemistry that studies VOCs is known as “Volatilomics”.

This Special Issue focuses on the methods employed in the isolation, separation and identification of VOCs related to biological systems. Manuscripts should focus on—but are not limited to—the following topics:

  • Sampling and preconcentration techniques, such as sorbent enrichment, membrane extraction and headspace techniques.
  • Miniaturized trapping devices.
  • Novel isolation techniques, such as ultrasound-assisted extraction, microwave-assisted solvent extraction, supercritical fluid extraction or subcritical water extraction.
  • Gas Chromatography Mass Spectrometry protocols for use in separation steps.
  • Non-chromatographic methods, such as chemiluminescence, infrared and Raman spectroscopic techniques.
  • Real-time Volatilomics: Proton transfer reaction MS and direct infusion MS techniques.
  • The application of chemometric methods.

Original research papers, reviews and short communications 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. 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.

Background: The cannabis plant or marijuana has been used since ancient times for different purposes. An increase in the content of THC in cannabis has been observed worldwide, whereas the CBD content is dropping. This study’s main goal was to categorize marijuana suspected policies’ seizures (MSPS) based on the cannabinoid component concentrations concerning their potency and age. Methods: The samples were MSPS seized in southeast Serbia from April 2019 to April 2020. The cannabinoid content was determined using gas chromatography with mass spectrometry. Descriptive statistics were performed using Linux LibreOffice Calc. Results: All of the samples had a THC content higher than 0.3%, thus classifying the samples as marijuana according to the Serbian Law on Psychoactive Controlled Substances. The highest concentration of THC was 16.10%, while the lowest was 4.90%. The highest average concentration of THC (12.39%) was found in the buds. Only 11.81% of the samples had a CBD concentration higher than 1%, making all other marijuana samples extremely psychoactive. Most of the samples were older than 2 years, according to the calculated CBN/THC ratio. Conclusion: Our results confirm trends regarding the dominance of THC content in contemporary cannabis worldwide. It is necessary to monitor trends of cannabis potency in Serbia continuously because of its location. Full article
