Py-GCxGC/MS in cultural heritage studies: An illustration through analytical characterization of traditional East Asian handmade papers

Authors: Bin Han Ghiz, lène Daheur, Michel Sablier Abstract We tested the performance of pyrolysis-comprehensive two-dimensional gas chromatography/mass spectrometry in the course of our cultural heritage studies, and compared its potentialities for the characterization of traditional East Asian handmade papers with those previously obtained by pyrolysis-gas chromatography/mass spectrometry. The evaluation of the two methods was …

Studies on the volatile fraction composition of three native Amazonian- Brazilian fruits: Murici (Byrsonima crassifolia L., Malpighiaceae), bacuri (Platonia insignis M., Clusiaceae), and sapodilla (Manilkara sapota L., Sapotaceae)

Authors: Thais M.Uekane, Luca Nicolotti, Alessandra Griglione, Humberto R. Bizzo, Patrizia Rubiolo, Carlo Bicchi, Maria Helena, M. Rocha-Leão, Claudia M. Rezende Abstract The volatile fraction of murici, bacuri and sapodilla are here studied because of their increasing interest for consumers, abundance of production in Brazil, and the general demand for new flavors and aromas. Their …

Identifying unknown by-products in drinking water using comprehensive two-dimensional gas chromatography quadrupole mass spectrometry and in silico toxicity assessment

Authors: Chunmei Li, Donghong Wang, Na Li, Qian Luo, Xiong Xu, Zijian Wang Abstract Improvements in extraction and detection technologies have increased our abilities to identify new disinfection by-products (DBPs) over the last 40 years. However, most previous studies combined DBP identification and measurement efforts with toxicology to address concerns on a few expected DBPs, making it …

Simultaneous analysis of polychlorinated biphenyls and polychlorinated naphthalenes by isotope dilution comprehensive two dimensional gas chromatography high-resolution time-of-flight mass spectrometry

Authors: Dan Xia, Lirong Gao, Minghui Zheng, Shasha Wang, Guorui Liu Abstract Polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs) are listed as persistent organic pollutants (POPs) under the Stockholm Convention. Because they have similar physical and chemical properties, they are coeluted and are usually analyzed separately by different gas chromatography high-resolution mass spectrometry (GC-HRMS) methods. …

Evaluation of poly (90% biscyanopropyl/10% cyanopropylphenylsiloxane) capillary columns for the gas chromatographic quantification of trans fatty acids in non-hydrogenated vegetable oils

Authors: Pierluigi Delmonte Abstract Current gas chromatographic (GC) methods for the analysis of fatty acids (FA) were optimized primarily for the quantification of the trans 18:1 FAs (18:1 tFAs) produced during the partial hydrogenation of fats and oils. Recent regulatory action regarding the application of partial hydrogenation in the processing of edible fats and oils may reshape the …
