Download or read book Gas Chromatography and Mass Spectrometry A Practical Guide written by O. David Sparkman and published by Academic Press. This book was released on 2011-05-17 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guide follows the highly successful first edition by F.G. Kitson, B.S. Larsen, and C.N. McEwen (1996), which was designed as an indispensible resource for GC/MS practitioners regardless of whether they are a novice or well experienced. The Fundamentals section has been extensively reworked from the original edition to give more depth of an understanding of the techniques and science involved with GC/MS. Even with this expansion, the original brevity and simple didactic style has been retained. Information on chromatographic peak deconvolution has been added along with a more in-depth understanding of the use of mass spectral databases in the identification of unknowns. Since the last edition, a number of advances in GC inlet systems and sample introduction techniques have occurred, and they are included in the new edition. Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass Spectral Interpretation of Specific Compound Types has the same number of compound types as the original edition, but the information in each section has been expanded to not only explain some of the spectra but to also explain why certain fragmentations take place. The number of Appendices has been increased from 12 to 17. The Appendix on Atomic Masses and Isotope Abundances has been expanded to provide tools to aid in determination of elemental composition from isotope peak intensity ratios. An appendix with examples on "Steps to follow in the determination of elemental compositions based on isotope peak intensities" has been added. Appendices on whether to use GC/MS or LC/MS, third-party software for use in data analysis, list of information required in reporting GC/MS data, X+1 and X+2 peak relative intensities based on the number of atoms of carbon in an ion, and list of available EI mass spectral databases have been added. Others such as the ones on derivatization, isotope peak patterns for ions with Cl and/or Br, terms used in GC and in mass spectrometry, and tips on setting up, maintaining and troubleshooting a GC/MS system have all been expanded and updated. Covers the practical instruction necessary for successful operation of GC/MS equipment Reviews the latest advances in instrumentation, ionization methods, and quantitation Includes troubleshooting techniques and a variety of additional information useful for the GC/MS practitioner A true benchtop reference A guide to a basic understanding of the components of a Gas Chromatograph-Mass Spectrometer (GC-MS) Quick References to data interpretation Ready source for information on new analyses

Download or read book Advances in Feature Selection in One and Two dimensional Gas Chromatography with Mass Spectrometry written by Kelsey Leigh Berrier and published by . This book was released on 2020 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: One- and two-dimensional gas chromatography coupled with mass spectrometry provides an enormous amount of quantitative data describing the chemical composition of complex samples. Besides quantification and identification of analytes, common analysis goals include classifying samples or predicting sample properties based upon the chemical information contained in the chromatographic data. The chemometric modeling techniques used to accomplish these goals often benefit from the removal of redundant or irrelevant chromatographic variables, which is achieved by feature selection. This dissertation presents several research studies detailing advances in and applications of feature selection applied to one- and two-dimensional gas chromatography with mass spectrometric detection. The two-dimensional mass cluster method was evaluated as a peak detection algorithm using simulations of gas chromatography coupled with time-of-flight mass spectrometry (GC-TOFMS) data under varying sample and separation complexity. An unsupervised feature selection method based on variance thresholding was applied to simulated GC-MS chromatograms and a previously studied yeast metabolome dataset. A successful application of partial least squares (PLS) regression analysis to comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC-TOFMS) for the prediction of bulk physical properties of kerosene-based fuels is included to demonstrate a case where feature selection was not required. Finally, supervised feature selection was implemented on GCxGC-TOFMS data of rocket fuels to aid in the prediction of fuel thermal integrity by PLS.

Download or read book Development of Instrumental and Computational Methods for Accessing Information in Multi dimensional Gas Chromatography with Mass Spectrometry written by Nathanial E. Watson and published by . This book was released on 2017 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three instrumental and computational methods are demonstrated in an endeavor to create novel techniques to extract information from the troves of data generated by multi-dimensional gas chromatography with mass spectrometry. Initially, these methods are considered within the context of targeted and non-targeted experimental design. The tile-based Fisher Ratio with null distribution analysis is first evaluated and validated within the non-targeted realm. The method is shown to be fast and accurate. Forty-six of the fifty-four benchmarked changing metabolites previously discovered were found by the new methodology while consistently excluding all but one of the benchmarked nineteen false positive metabolites previously identified. This was achieved in less than 5% of the time required for the previous method. Later, the three-dimensional gas chromatograph is improved to include mass spectrometric detection. This instrument provides four dimensions (4D) of chemical selectivity and includes significant improvements to total selectivity (mass spectrometric and chromatographic), peak identification, and operational temperature range relative to previous models of the GC3 reported. Useful approaches to visualize the 4D data are presented. The GC3 - TOFMS instrument experimentally achieved total peak capacity, nc,3D, ranging from 5000 to 9600 (x̅= 7000, s = 1700) for 10 representative analytes for 50 min separations with component dimensional peak capacities averaging 406, 3.6, and 4.9 for 1D, 2D, and 3D, respectively. Using this instrument and the well understood Parallel Factor Analysis (PARAFAC) model a new option for targeted analysis is presented. Conceptualizing the GC3 - TOFMS as a one-dimensional gas chromatograph with GC × GC-TOFMS detection the instrument was allowed to create the PARAFAC target window natively. Each first dimension modulation thus created a full GC × GC-TOFMS chromatogram totally amenable to PARAFAC. A simple mixture of 115 compounds and a diesel sample were interrogated through this methodology. All test analyte targets were successfully identified in both mixtures. In addition, mass spectral matching of the PARAFAC loadings to library spectra yielded results greater than 900 in 40 of 42 test analyte cases. Twenty-nine of these cases produced match values greater than 950.
