Описание: Provies an introduction to chromatography. Chromatography has become a cornerstone of separation science, that branch of chemistry devoted to separating compounds from mixtures. There are two main categories of chromatography: preparative and analytical. Analytical work uses small sample sizes; preparative work uses large quantities of samples and collects the output in bulk.

Описание: During recent years there has been increasing interest in the value of a number of chemical and physical-chemical analytical methods for the detection and characterization of microorganisms. Furthermore, such methods are currently used in studies on microbial metabolic processes, on the role of microorganisms in the turnover of inorganic and organic compounds, and on the impact on environmental changes by microbial activity. Moreover, the introduction of some of these methods not only shortens the analytical time period compared to ·'traditional" techniques, but also improves the analytical quality. Mass spectrometry (MS) combined with chromatographic inlet systems, particularly gas chromatography (GC), belongs to those methods which during recent years have established their value for the above-mentioned purposes. The present volume starts with basic chapters on the principles for MS and common inlet systems, particulary Gc. It discusses applications of these techniques to a number of microbiological disciplines, e.g., ecologi cal and medical microbiology. Emphasis is laid on organic compound classes vii viii / PREFACE of special relevance to microbiology, e.g., volatiles, lipids, amino acids, peptides and carbohydrates. Some compound classes of a more general biochemical rather than specific microbiological importance, e.g., steroids and nucleotides, are dealt with briefly. The editors wish to thank all those who have contributed to this book. We hope it will stimulate further research in this futuristic field and will be of practical value.

Описание: Gas chromatography is a term used to describe the group of analytical separation techniques used to analyse volatile substances in the gas phase. In gas chromatography, the components of a sample are dissolved in a solvent and vaporised in order to separate the analyses by distributing the sample between two phases: a stationary phase and a mobile phase. The mobile phase is a chemically inert gas that serves to carry the molecules of the analyse through the heated column. Gas chromatography is one of the sole forms of chromatography that does not utilise the mobile phase for interacting with the analyse. The stationary phase is either a solid adsorbent, termed gas-solid chromatography (GSC), or a liquid on an inert support, termed gas-liquid chromatography (GLC). Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations. This inert gas goes through a glass column packed with silica that is coated with a liquid. Materials that are less soluble in the liquid will increase the result faster than the material with greater solubility. The purpose of this book is to provide a better understanding on its separation and measurement techniques and its application. Since chromatography techniques are separating and analysing methods, this book will help other researchers and young scientists to choose a suitable chromatography technique. Furthermore, this book illustrates the newest challenges in this area. This valuable book aims to provide a connection between various chromatography techniques and different processes.

This is the first book that comprehensively and systematically describes the new technology of hydrophilic interaction liquid chromatography (HILIC). Hydrophilic interaction chromatography is a separation technique suitable for polar and hydrophilic compounds and orthogonal to reversed phase liquid chromatography. From small organic molecules to proteins, the text explores the many applications of HILIC in the analytical field. Winner of the President's Award for Excellence, the author explains how HILIC can significantly improve analytical throughput by shortening sample preparation procedure, which is one of the bottlenecks for drug discovery and development in the pharmaceutical industry.

Effective measurement of the composition and properties of petroleum is essential for its exploration, production, and refining; however, new technologies and methodologies are not adequately documented in much of the current literature. Analytical Methods in Petroleum Upstream Applications explores advances in the analytical methods and instrumentation that allow more accurate determination of the components, classes of compounds, properties, and features of petroleum and its fractions.
Recognized experts explore a host of topics, including:
A petroleum molecular composition continuity model as a context for other analytical measurements
A modern modular sampling system for use in the lab or the process area to collect and control samples for subsequent analysis
The importance of oil-in-water measurements and monitoring
The chemical and physical properties of heavy oils, their fractions, and products from their upgrading
Analytical measurements using gas chromatography and nuclear magnetic resonance (NMR) applications
Asphaltene and heavy ends analysis
Chemometrics and modeling approaches for understanding petroleum composition and properties to improve upstream, midstream, and downstream operations
Due to the renaissance of gas and oil production in North America, interest has grown in analytical methods for a wide range of applications. The understanding provided in this text is designed to help chemists, geologists, and chemical and petroleum engineers make more accurate estimates of the crude value to specific refinery configurations, providing insight into optimum development and extraction schemes.
