Book Description
Gas Chromatography, Second Edition, offers a single source of authoritative information on all aspects relating to the practice of gas chromatography. A focus on short, topic-focused chapters facilitates the identification of information that will be of immediate interest for familiar or emerging uses of gas chromatography. The book gives those working in both academia and industry the opportunity to learn, refresh and deepen their understanding of fundamental and instrumental aspects of gas chromatography and tools for the interpretation and management of chromatographic data. Users will find a consolidated guide to the selection of separation conditions and the use of auxiliary techniques. This new edition restores the contemporary character of the book with respect to those involved in advancing the technology, analyzing the data produced, or applying the technique to new application areas. New topics covered include hyphenated spectroscopic detectors, micromachined instrument platforms, derivatization and related microchemical techniques, petrochemical applications, volatile compounds in the atmosphere, and more. - Includes chapters written by recognized authoritative and visionary experts in the field, thus providing an overview and focused treatments on a single topic - Provides comprehensive coverage of modern gas chromatography, from theory, to methods and selected applications - Places modern developments in research literature into a general context not always apparent to inexperienced users of the techniques

Book Description
Particle separation from hot gases is a challenging task, especially for nanoparticles. Therefore, it is usually avoided by quenching the hot gas to conduct particle separation at a more convenient temperature. In these cases, valuable high-caloric heat is either not utilized at all or only inefficiently because of particle deposition on the heat exchanger surfaces. Valuable potential is thus wasted, as high-temperature processes are already an essential part of many industries and become increasingly relevant for other industrial sectors (e.g., pyrolytic processes in the circular economy). To reduce operating costs and environmental impact, the efficient use of resources (especially fossil fuels) is an absolute necessity. To tackle this pending problem, the concept of high-temperature electrostatic precipitation is investigated in this doctoral thesis. In an electrostatic precipitator, particles are charged by charge carriers produced in a corona discharge near the discharge electrode. Charged particles migrate due to the electric field and subsequently precipitate onto the collection electrode. This doctoral thesis clearly demonstrates the feasibility of nanoparticle removal from hot gases at up to 1073 K (800 °C) using electrostatic precipitation while presenting novel insights into the charge carrier properties and their distribution, the influence of thermionic emission on the operation of electrostatic precipitators, and the fundamentals of particle charging at high temperatures.

Book Description
Over the last decade, scientific and engineering interests have been shifting from conventional ion mobility spectrometry (IMS) to field asymmetric waveform ion mobility spectrometry (FAIMS). Differential Ion Mobility Spectrometry: Nonlinear Ion Transport and Fundamentals of FAIMS explores this new analytical technology that separates and characterizes ions by the difference between their mobility in gases at high and low electric fields. It also covers the novel topics of higher-order differential IMS and IMS with alignment of dipole direction. The book relates the fundamentals of FAIMS and other nonlinear IMS methods to the physics of gas-phase ion transport. It begins with the basics of ion diffusion and mobility in gases, covering the main attributes of conventional IMS that are relevant to all IMS approaches. Building on this foundation, the author reviews diverse high-field transport phenomena that underlie differential IMS. He discusses the conceptual implementation and first-principles optimization of FAIMS as a filtering technique, emphasizing the dependence of FAIMS performance metrics on instrumental parameters and properties of ion species. He also explores ion reactions in FAIMS caused by field heating and the effects of inhomogeneous electric field in curved FAIMS gaps. Written by an accomplished scientist in the field, this state-of-the-art book supplies the foundation to understand the new technology of nonlinear IMS methods.
