doi: 10.1016/j.fct.2018.05.021. Epub 2018 May 8. Authors Camila 2020-11-23 2019-10-21 2019-11-26 The analyses were carried out by UPLC-MS-QTOF. The use of high resolution mass spectrometry allowed the structural elucidation of these compounds and their correct identification. The main oligomers identified were cyclic as well as lineal from the first, second, and third series.

FAQ; Get in Touch with Us A benchtop QTof mass spectrometer incorporating the XS Collision Cell for enhanced sensitivity and selectivity, resulting in the highest quality, most comprehensive qualitative information together with the ultimate in quantitative performance. 2018-02-10 · UPLC-MS-QTOF is very useful for the determination of oligomer content in PET samples as well as the presence of non-volatile additives and other NIAS. The identified oligomers have shown to be able to migrate to food simulants in the studied samples, and this fact confirms the importance of knowing the oligomer composition in the raw material.

HMDB ID: HMDB0000014. Compound name: Deoxycytidine. Spectrum type: LC- MS/MS Spectrum - LC-ESI-QTOF (UPLC Q-Tof Premier, Waters) , Negative.

Tandem MS can be performed as part of this method. In this work the “omics” interface was validated with a set of 37 wines; 42 biomarkers were extracted from GC-MS and 152 from UPLC-MS-QTOF. The development of tools such as network reconstruction provided considerable amount of information that contributed to the understanding of the kinetic contexts of the molecules (through ageing time).

UPLC-qTOF-MS is a feasible technique for characterization of chlorogenic acid profile.. M. ovalifolia contains large amounts of cis-geometrical isomers of chlorogenic acids. Paired with our industry-leading ACQUITY UPLC System, the Xevo QTof MS System gives you the performance to enable you to capture all of the data all of the time. The processing technology employed in traditional Chinese medicine (TCM) is significant and distinct. Meanwhile, the processed Coptis chinensis Franch. are significant in clinic based on clinical practice and literature.
