Special Issue Information

Dear Colleagues,

In recent years, highly efficient separation or separation-free analytical methods have played an increasingly vital role in rubber plant research for potential industrial utilizations,  and great scientific and technological advances have been achieved in the development and optimization of highly efficient separation or separation-free methods, which are useful for plant rubber/non-rubber component analysis and molecular characterization.

This Special Issue will include both well-drafted manuscripts providing an overview of current knowledge regarding highly efficient separation or separation-free analytical methods and analytical procedures, as well as experimental investigations utilizing novel techniques with advanced materials or instrumental devices to address specific analytical interests throughout plant rubber/non-rubber component analysis and the molecular characterization process.

The aim of this Special Issue is not only to provide a general overview of the modern analytical separation or separation-free methods used to analyze and characterize various plant rubber/non-rubber components, but also to outline the current research trends in these methods and thus acquaint the scientific community with modern analytical procedures and approaches, e.g., chromatographic targeted quantitation or non-targeted profiling/screening practices.

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.

Taraxacum kok-saghyz (TKS), a rubber-producing plant with excellent potential, emerges as a viable substitute for rubber tree (Hevea brasiliensis). While natural rubber is a desirable material, conventional techniques for assessing rubber content have faced challenges in meeting practical production requirements. To address this issue, we have developed a pyrolysis–mass spectrometry (PY-MS) instrument for the quantitative evaluation of natural rubber (NR) content in rubber-producing plants. The derived standard curve equation, established for the detection of TKS dry weight through external standard calibration, demonstrates a correlation coefficient (R2) surpassing 0.99. The method exhibits commendable recovery rates (93.27–107.83%), relative standard deviations (RSD ≤ 3.93%), and a swift analysis time of merely 10 min per sample, thereby enabling accurate and efficient quantification of NR dry weight. Additionally, the PY-MS system we designed can be modified for vehicular use, enabling on-site, in situ analysis, and it provides substantial support for TKS breeding and propagation efforts. This approach possesses significant potential for extensive utilization in the assessment of rubber content in rubber-producing plants other than TKS. The integration of pyrolysis–mass spectrometry for the identification of polymers with high molecular weight offers a valuable pathway for the examination of diverse polymers. Full article
