Special Issue Information

Dear Colleagues,

It is a pleasure to announce the next Separations Special Issue entitled “Comprehensive Separations of Complex Mixtures by Gas Chromatography/Mass Spectrometry (Volume II)”, which will compile the state-of-the-art methods developed in this area.

The current trends in analytical chemistry are focused on the search for comprehensive, sensitive, robust, simple, and fast methodologies that lead to the simultaneous determination of a huge number of compounds at low levels of concentration with the maximum reliability possible and also complying with the requirements of sustainability proposed by green analytical chemistry and white analytical chemistry. In this sense, conventional gas chromatography, two-dimensional gas chromatography and, more recently, very and ultra-fast gas chromatography coupled to different types of mass spectrometry analysers are excellent tools for accomplishing this goal in many fields.

The aim of this publication is to present the most recent applications of gas chromatography coupled to mass spectrometry in the analysis and evaluation of different complex samples, as well as to provide a wide and accurate overview of recent advances and future trends related to this topic.

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.

Bamboo vinegar is a liquid biomass with a huge yield and complex chemical composition. At present, the relative quantification of bamboo vinegar has been investigated in most studies. To analyze twelve compounds from bamboo vinegar simultaneously, gas chromatography-mass spectrometry and an external standard method were used to develop an analytical method. In this method, chromatographic separations of all compounds were above 1.5. The linear range was between 0.100 and 10.000 mg/L, and the coefficient of determination (R2) was between 0.9981 and 0.9997, indicating a good linear relationship. The limit of detection (LOD) was between 0.004 and 0.780 mg/L; the limit of quantitation (LOQ) was between 0.016 and 3.120 mg/L; the relative standard deviations (RSDs) of instrument precision and method stability were less than 8%; the recovery rate was between 89.25% and 113.77%, and its RSD was between 0.44% and 5.70%. Using this method, fourteen bamboo vinegars and six wood vinegars were analyzed, and it was found that the content of propionic acid, phenol, and 2-methoxyphenol was higher in most samples. In addition, the differences in physicochemical properties between distilled bamboo vinegar and its original solution after atmospheric distillation were investigated. Full article
