2.3. Development of the database LC-TOF-QUANT 2012-11-22 Resolution LC-QTOF/MS-Based Metabolomics Approach Dae-Young Lee 1, Jae Kwang Kim 2, Sabina Shrestha 3, Principal component analysis (PCA) was employed to observe dissimilarities and elucidate how quality discrimination is resolved in correlation with influential factors. High-resolution mass spectrometry is a powerful tool in clinical analysis but remains less explored due to its lower dynamic range and sensitivity compared to triple quadrupoles. Glycated hemoglobin (HbA1c) is the current gold standard biomarker to monitor the control of diabetes, representing long-term plasma glycemic levels. Due to its clinical importance, several methods have been developed Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

determined by LC-QToF-MS, a statistical tool such as principal components analysis (PCA) needs to be used in order to reduce the large set of variables that arise to a small set that still contains most of the information in Fthe large set. PCA is a mathematical procedure that transforms a large number of (possibly) correlated variables into a 2016-06-16 of data acquired in the LC-QTOF-MS. Statistics capabilities used in this study included principal component analysis, principal component variable grouping and t-test. The results of the t-test indicated how well each variable (mass) distinguished the two groups (control and case), which had been previously assigned to each sample. 2020-02-07 Chemical Profiling of the Aerial Parts and Roots of Ixeris dentata Using LC-QTOF-MS Combined with Multivariate Chemometric Analysis Park JH, Park SJ, Yoo G, Kwak HJ, Oh Y and Kim SH* College of Pharmacy, Yonsei Institute of Pharmaceutical Science, Yonsei University, 85 Songdogwahak-ro, Yeonsu-gu, Incheon 21983, Korea 2019-08-01 LC-QTOF/MS metabolomic profiles in human plasma after a 5-week high dietary fiber intake LC-QTOF/MS metabolomic profiles in human plasma after a 5-week high dietary fiber intake Johansson-Persson, Anna; Barri, Thaer; Ulmius, Matilda; Önning, Gunilla; Dragsted, Lars 2013-03-28 00:00:00 Anal Bioanal Chem (2013) 405:4799–4809 DOI 10.1007/s00216-013-6874-5 RESEARCH PAPER LC-QTOF/MS … Retrospective LC‐QTOF‐MS analysis searching for pharmaceutical metabolites in urban wastewater Retrospective LC‐QTOF‐MS analysis searching for pharmaceutical metabolites in urban wastewater Hernández, Félix; Ibáñez, María; Gracia‐Lor, Emma; Sancho, Juan V. 2011-12-01 00:00:00 1 Introduction In last few years, there has been an increasing concern over the presence of emerging The TripleTOF 5600+ System combines SCIEX Triple Quad technology with the Accelerator TOF Analyzer, to deliver nominal mass and accurate mass benefits in a single platform.
