Metabolomics and the Development of Nontarget Discovery Analysis Methods for Two-dimensional Gas Chromatography Time-of-flight Mass Spectrometry
Author: Luke Marney
Publisher:
ISBN:
Category : Chemistry, Analytic
Languages : en
Pages : 153
Book Description
Two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC x GC - TOFMS) is a highly capable instrumental platform that produces complex and information-rich multi-dimensional chemical data. The complex data is computationally overwhelming, especially when many samples are analyzed with multiple injections for each sample. The highly information rich data from GC x GC - TOFMS benefits from elegant and comprehensive target and nontarget algorithmic methods. The development of a novel tile-based Fisher ratio method that greatly decreases the false-positive rate is described thoroughly in this dissertation. Also, the initially application of currently available instrumental and data analysis methods to the optimization of the preparation of mouse heart tissue metabolomics and the investigation of the pathophysiology of pressure overload hypertrophy is described herein. Then, novel algorithmic methods to solve issues seen with the difficult pixel-based analysis are described. Overall, GC x GC - TOFMS and the related data analysis tools investigated here aim to reduce the complex chemical data to glean the most meaningful information from an experiment.

Publisher: Springer Science & Business Media
ISBN: 3540297820
Category : Science
Languages : en
Pages : 351
Book Description
Metabolomics – which deals with all metabolites of an organism – is a rapidly-emerging sector of post-genome research fields. It plays significant roles in a variety of fields from medicine to agriculture and holds a fundamental position in functional genomics studies and their application in plant biotechnology. This volume comprehensively covers plant metabolomics for the first time. The chapters offer cutting-edge information on analytical technology, bioinformatics and applications. They were all written by leading researchers who have been directly involved in plant metabolomics research throughout the world. Up-to-date information and future developments are described, thereby producing a volume which is a landmark of plant metabolomics research and a beneficial guideline to graduate students and researchers in academia, industry, and technology transfer organizations in all plant science fields.

Advanced Chemometric Techniques for the Analysis of Complex Samples Using One- and Two-dimensional Gas Chromatography Coupled with Time-of-flight Mass Spectrometry
Author: Brooke C. Reaser

ISBN:
Category :
Languages : en
Pages : 172
Book Description
Gas chromatography is a powerful separation technique that alone, and when coupled with mass spectrometric detection, can provide detailed information regarding the chemical composition of complex mixtures. Advanced chemometric algorithms are often applied to the data generated from these gas chromatographic separations in order to glean additional meaningful information from large and complex data sets. This dissertation presents several research investigations conducted on the development, optimization, application and study of several chemometric algorithms applied to one- and two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (TOFMS). The two-dimensional mass cluster method and principal component analysis (PCA) were applied to a non-targeted investigation of the stable-isotope incorporation of metabolites present in the metabolome of the methylotrophic bacteria Methylobacterium extorquens AM1 using gas chromatography time-of-flight mass spectrometry (GC-TOFMS). The area under the curve (AUC) of receiver operating characteristic (ROC) curves were used as quantitative metrics for the optimization of the tile-based Fisher ratio method using diesel fuel spiked with native and non-native analytes using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC × GC – TOFMS). This optimized algorithm was then applied to a process analytical chemistry (PAC) investigation into the source of catalyst yield reduction in an industrial polymerization plant. Finally, a GC-TOFMS simulation-based study determined the chemometric limit of resolution for deconvoluting analytes using multivariate curve resolution alternating least squares (MCR-ALS) and compared the results to expected theory surrounding the probability of peak overlap.
