Book excerpt: A further development of the procedure based on pyrolysis-gas chromatography (Py-GC) for the characterization of plastic bonded explosives (PBX's) is described. After grinding, the PBX samples were pressed on a pyrolysis wire followed by Py-GC analysis. The peak areas obtained were normalized and submitted to multivariate data analysis. The use of principal component analysis (PCA) was tested on 5 samples which differed slightly in composition and age. The results were promising and showed that PCA is a powerful tool for the differentiation between PBX samples. The pressure by which the samples were pressed on the pyrolysis wire appeared to be an important parameter. This parameter was optimized together with the pyrolysis temperature and the amount of sample. The optimization experiment was carried out with 2 PBX samples which differed only in crosslink density. It turned out that it was difficult to find optima in the parameters resulting in a maximal difference between the 2 samples. The following settings of the parameters were selected: 5.2 tonnes, 75 mg and 610 C.

Book excerpt: Applications of the developed procedure based on pyrolysis-gas chromatography (Py-GC) and principal component analysis (PCA) for the characterization of plastic bonded explosives (PBX's) are described. Due to difficulties with the commonly used normalization method a new normalization method was developed and applied in this investigation. The patterns in the score plots obtained after PCA of the Py-GC results appeared much clearer using this new method. PBX samples were examined on homogeneity, influence of the amount of antioxidant (Flexzone) and the crosslink density. It appears that PBX's were inhomogeneous despite a thorough mixing of the constituents during the preparation. Aging experiments were performed on samples which differed in the amount of Flexzone and in the crosslink density. As more Flexzone was added the change in the pattern of the GC-peaks became less. No relation could be found between the stability of PBX's and the crosslink density. Finally, a comparison was made between Dutch samples and samples from the UK and Norway. Small differences were observed between the samples from the three nations.

Book excerpt: The methodology of analytical pyrolysis-GC/MS has been known for several years, but is seldom used in research laboratories and process control in the chemical industry. This is due to the relative difficulty of interpreting the identified pyrolysis products as well as the variety of them. This book contains full identification of several classes of polymers/copolymers and biopolymers that can be very helpful to the user. In addition, the practical applications can encourage analytical chemists and engineers to use the techniques explored in this volume.The structure and the functions of various types of pyrolyzers and the results of the pyrolysis-gas chromatographic-mass spectrometric identification of synthetic polymers/copolymers and biopolymers at 700°C are described. Practical applications of these techniques are also included, detailing the analysis of microplastics, failure analysis in the automotive industry and solutions for technological problems.

Available in PDF, EPUB and Kindle. Book excerpt: In this data book, both conventional Py-GC/MS where thermal energy alone is used to cause fragmentation of given polymeric materials and reactive Py-GC/MS in the presence of organic alkaline for condensation polymers are compiled. Before going into detailed presentation of the data, however, acquiring a firm grip on the proper understanding about the situation of Py-GC/MS would promote better utilization of the following pyrolysis data for various polymers samples. This book incorporates recent technological advances in analytical pyrolysis methods especially useful for the characterization of 163 typical synthetic polymers. The book briefly reviews the instrumentation available in advanced analytical pyrolysis, and offers guidance to perform effectually this technique combining with gas chromatography and mass spectrometry. Main contents are comprehensive sample pyrograms, thermograms, identification tables, and representative mass spectra (MS) of pyrolyzates for synthetic polymers. This edition also highlights thermally-assisted hydrolysis and methylation technique effectively applied to 33 basic condensation polymers. - Coverage of Py-GC/MS data of conventional pyrograms and thermograms of basic 163 kinds of synthetic polymers together with MS and retention index data for pyrolyzates, enabling a quick identification - Additional coverage of the pyrograms and their related data for 33 basic condensation polymers obtained by the thermally-assisted hydrolysis and methylation technique - All compiled data measured under the same experimental conditions for pyrolysis, gas chromatography and mass spectrometry to facilitate peak identification - Surveyable instant information on two facing pages dedicated to the whole data of a given polymer sample

Book excerpt: Analytical Pyrolysis presents the Proceedings of the Third International Symposium on Analytical Pyrolysis, held in Amsterdam on September 7-9, 1976. It looks at newly emergent techniques in analytical pyrolysis, including pyrolysis mass spectrometry, gas chromatography, thin-layer chromatography, and pyrolysis-gas liquid chromatography. The book also covers topics ranging from automation and microbiology to forensic science and pharmacology, reproducibility and specificity, biochemistry, laser-induced pyrolysis, pyrolytic reaction mechanisms, and polymers. Comprised of 50 chapters, this book begins with a discussion of automatic analysis of tire rubber blends using computer-linked pyrolysis gas chromatography, thermal procedures in coupling with thin-layer chromatography, the role of pyrolysis-gas liquid chromatography in biomedical studies, and the identification of microorganisms by pyrolysis gas-liquid chromatography. It then examines forensic applications of analytical pyrolysis techniques, structure and degradation behavior of synthetic polymers using pyrolysis in combination with field ion mass spectrometry, determination of polysaccharides in fulvic acids by pyrolysis gas chromatography, and application of Curie-point pyrolysis mass spectrometry in fungal taxonomy. The reader is also introduced to pyrolysis mass spectrometry of model compounds labeled with stable isotopes, the use of pyrolysis/gas chromatography to determine the quality of porous polymers of styrene cross-linked with divinyl benzene, and application of pyrohydrolysis for a rapid and accurate determination of halides in silicate rocks and minerals. This volume will benefit students, researchers, chemists, and scientists working in the field of analytical pyrolysis.
