Available in PDF, EPUB and Kindle. Book excerpt: A system has been developed whereby a pyrogram may be obtained for each separated component in a gas chromatographic effluent. These pyrograms may be used for "fingerprint" identifications of the peaks on a chromatogram. During the development of this system the characteristics of a low- pressure-drop packed column were examined as well as gas phase pyrolysis and rapid temperature programming. Linear temperature programming with program rates up to 400°C per minute was developed and used with a wide range of carrier gas flow rates. Retention temperatures predicted from isothermal data were verified. The importance of correc tly specifying the flow rate during rapid temperature programming became apparent during the investigation when predicted retention temperatures were otherwise less than the experimentally observed values. Pyrolyzer design for gas phase pyrolysis was considered. The temperature profile for a tubular pyrolyzer was examined experimentally. The effects of temperature and residence time on gas phase pyrolysis were studied using several hydrocarbons.

Book excerpt: A pyrolysis gas chromatography method for the rapid identification of organic polymers is described. Previous pyrolysis GLC studies have involved single flow systems and the identity of the small and large components of the pyrolyzate could not be determined simultaneously. The method described here makes use of a Chemical Data Systems Pyrochro which separates the pyrolyzate into a dual flow system equipped with thermal conductivity and flame ionization detectors. This arrangement permits the determination of both the small and large components present under optimum conditions. A linear temperature program is used to resolve the higher boiling components of the pyrolyzate in a reasonable time. The pyrograms obtained not only offer a fingerprint of the polymer, but also enable a detailed qualitative and quantitative analysis of the fragments of the pyrolyzate. The results of studies on some classes of elastomers, thermoplasts and fabrics are reported here. The polymer classes investigated include polyolefins, polyester, polyurethanes, polyethers, polyamides, phenolics, polycarbohydrates, epoxy resins and polycarbonates. (Author-PL).

This book approaches the topic of sample preparation in chromatography in a methodical way, viewing it as a logical connection between sample collection and analytical chromatography. Providing a guide for choosing the appropriate sample preparation for a given analysis, this book describes various ways to process the sample, explaining the principle, discussing the advantages and disadvantages, describing the applicability to different types of samples, and showing the fitness to specific chromatographic determinations. The first part of the book contains an overview of sample preparation showing its relation to sample collection and to the core chromatographic analysis. The second part covers procedures that do not use chemical modifications of the analyte and includes methods for sample dissolution, concentration and cleanup designed mainly for modifying the initial matrix of the sample. This part starts with conventional separations such as filtration and distillation and finishes with more advanced techniques such as solid phase extraction and electroseparations. The third part gives a description of the chemical modifications that can be performed on a sample either for fractionation purposes or to improve a specific property of the analyte. This part includes derivatizations, polymer chemical degradations, and pyrolysis.

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

Furthermore the reader will understand the concepts of injection techniques and get a knowledge of the sources of error. The handbook also includes many practical guidelines. From reviews of former editions: "This substantial book is on injection techniques alone, which ... demonstrates this can have many pitfalls ... no one should be allowed to direct a laboratory doing quantitative analysis by GC without first being thoroughly familar with this book ..." The Analyst "This is a detailed reference volume filled with practical suggestions and techniques for managing split and splitless injection in the day-to-day world of the working gas chromatographer. It will be useful ... for anyone who must work hands-on with GC." Journal of High Resolution Chromatography
