This book was released on 2018 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometry (MS) has been a powerful technique for the characterization of synthetic polymers especially after the introduction of soft ionization methods such as electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). One-dimensional MS analysis provides molecular weight information by detection of the mass-to-charge (m/z) ratio of gas-phase analyte ions. However, tandem MS (MS/MS) capabilities, which involve separation and subsequent fragmentation of a selected analyte ion, are needed to obtain more detailed structural information. MS/MS can provide essential information on the backbone connectivity for synthetic polymers. For the sequence analysis of polymers having hydrocarbon backbones, multistage fragmentation (MSn) that combines different ion activation methods may be necessary. In addition to MS or MS/MS analysis, additional dimensions of separation can be achieved by online hyphenation of various dispersion techniques which allows for the investigation of more complex materials and mixtures. While online combination of liquid chromatography (LC) with MS has been the most common hyphenated technique, ion mobility (IM) spectrometry has been emerging as a much more rapid alternative method for the separation of gas-phase analyte ions based on their charge state, size, and architectural differences. These two separation techniques can be combined in a high-throughput 3D LC-IM-MS method or utilized separately depending on the sample complexity. In this dissertation, applications of MSn and hyphenated MS techniques are illustrated for the analysis of synthetic polymers and complex synthetic polymer-protein conjugates. In Chapter IV, various MSn approaches were investigated for the in-depth structural characterization of poly(N-isopropylacrylamide)s (pNIPAM). Different ion activation methods including collisionally activated dissociation (CAD) and electron transfer dissociation (ETD) provided structural information on end group and side chain functionalities. Sequential application of these ion activation methods in an MS3 fashion was necessary to obtain -C-C- bond cleavages and elucidate the backbone connectivity. In Chapter V, various hyphenated techniques that involve IM and LC were examined for the qualitative structural characterization of synthetic polymer-protein conjugates that were prepared by covalent attachment of poly(ethylene glycol) (PEG) to different proteins (PEGylation). The 3D LC-IM-MS technique was combined with in-source dissociation (ISD) for the site-specific characterization of PEGylated insulin with or without pretreatment of the sample.Finally, in Chapter VI, a methodology for occupancy analysis of PEGylated proteins was investigated on a model PEGylated myoglobin conjugate. Contrary to the qualitative approach discussed in Chapter V, the method presented in this final chapter involved a subtractive relative quantification by LC-MS which provided complete occupancy information on each possible PEG attachment site.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this thesis was to gain in-depth structural information of synthetic polymers by the application of several combined techniques. The second chapter provides an overview about the influence of the polymer architecture on its characterization by mass spectrometry and complementary methods. In the third chapter, we demonstrate the use of MS, more specifically MALDI-ToF MS, which provides molar masses and dispersity values for poly(furfuryl glycidyl ether) (PFGE). The second example is the study of poly(N-isopropyl acrylamide) (PNiPAm) copolymers with glyco-monomers with specific combinations of matrices and cationization agents. The fourth chapter will combine three different examples regarding linear, star-shaped and hybrid polymers, which were analyzed by advanced techniques. The linear copolymers were analyzed by separating them according to their chemical heterogeneity using liquid absorption chromatography at critical conditions (LACCC) of poly(2-ethyl-2-oxazoline) (PEtOx), followed by automated spotting onto a MALDI target, which was subsequently analyzed by MALDI. Secondly, star-shaped polymers: [poly(ethylene oxide) (PEO)-b-PEtOx]8 were monitored firstly by using LACCC of linear PEO as first separation dimension and furthermore injected onto an SEC column confirming the molar mass. Lastly, a hybrid PEO star-shaped polymer was investigated using MALDI to verify the complete functionality of the core with PEO arms. Finally, the last chapter will focus on the creation of a software to obtain information regarding average composition, overcoming isotopic, overlapping peaks and isobaric species from MS spectra. Moreover, the quantitative studies were carried out by correction of the mass discrimination and isotopic abundance. Consequently, advanced analytical techniques such as different ionization techniques within MS, a range of chromatographic hyphenation and computational methods are implemented for elucidating the complexity of synthetic polymers.

Available in PDF, EPUB and Kindle. Book excerpt: Polymers continue to play an ever increasing role in the modern world. In fact it is quite inconceivable to most people that we could ever have existed of the increased volume and variety of materials without them. As a result currently available, and the diversity of their application, characterisation has become an essential requirement of industrial and academic laboratories in volved with polymeric materials. On the one hand requirements may come from polymer specialists involved in the design and synthesis of new materials who require a detailed understanding of the relationship between the precise molecular architecture and the properties of the polymer in order to improve its capabilities and range of applications. On the other hand, many analysts who are not polymer specialists are faced with the problems of analysing and testing a wide range of polymeric materials for quality control or material specification purposes. We hope this book will be a useful reference for all scientists and techno or industrial laboratories, logists involved with polymers, whether in academic and irrespective of their scientific discipline. We have attempted to include in one volume all of the most important techniques. Obviously it is not possible to do this in any great depth but we have encouraged the use of specific examples to illustrate the range of possibilities. In addition numerous references are given to more detailed texts on specific subjects, to direct the reader where appropriate. The book is divided into II chapters.

Download or read book Modern Techniques for Polymer Characterisation written by R. A. Pethrick and published by John Wiley & Sons. This book was released on 1999-07-09 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking an interdisciplinary perspective, this volume provides a unique insight into the principal characterisation techniques available for determining the size of macromolecules in solution, their structural sequences and molecular weight. Recognition of macromolecules as a distinct state of matter owes much to the availability of various techniques for molar mass characterisation. In recent years, significant progress has been made into refining and developing these techniques but there has been a need for a volume that describes all the principal characterisation techniques and their relevance to various types of material. This book reflects some of the most recent advances and covers such techniques as: * Temperature rising elution fractionation * Field flow fractionation * Static and dynamic light scattering * Neutron scattering * Vapour Pressure Osmometry/Viscometry * Ultrafugation and Sedimentation * Gel Electrophoresis of Biological Macromolecules * Mass Spectrometry of Polymers The book will be invaluable for all those who are concerned with the study and use of macromolecular materials. It describes the developments that have been made in methods for molar mass characterisation and also the size of molecules in solution and solid phases. As the problem of molar mass characterisation is common to synthetic and biological polymers, this book will be of interest not only to polymer chemists, engineers and technologists, but also for biologists and scientists in numerous allied disciplines.
