Download or read book Selective Gas Chromatographic Detection of Vapor Phase Organics in Ambient Air written by JW. Bozzelli and published by . This book was released on 1980 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution capillary-column gas chromatography (GC) efficiently separates the many organic compounds that exist in ambient air. However, the identification of these compounds by retention times alone is difficult. The response ratios of sample components on several different types of GC detectors can be used to identify selected peaks more positively. Electron capture (ECD), photoionization (PID), and flame ionization (FID) detectors have been evaluated in this study. Samples split between an ECD and FID are readily analyzed for such electron-capturing species as carbon tetrachloride and tetrachloroethylene. Replicate samples are run on a PID for identification of peaks due to aromatic compounds and other unsaturated materials. This system of three detectors gives sufficient information to confirm the identity of the compounds that have been chosen for quantitation.
Download or read book Selective Detection in Gas Chromatography written by Edward W. Pitzer and published by . This book was released on 1987 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution gas chromatography (HRGC) is capable of separating a very complex hydrocarbon liquid such as jet propulsion fuel into nearly all of its individual components. However, there is no guarantee that what appears to be a single chromatographic peak is in fact a single fuel component. The method of detecting these HRGC eluents is very often the flame ionization detector (FID), a very sensitive and universally responding hydrocarbon detector. Neither the separating power of HRGC, or the sensitivity of the FID, however, lend information as to the identity of the eluting component. The need to specifically identify HRGC eluents, especially those containing heteroatoms such as nitrogen, sulfur, phosphorus, oxygen, halogens and some materials has been well-documented. The purpose of this report is to review the progress in the area of selective gas chromatographic detectors and to recommend selective detectors for use in the HRGC analysis of jet propulsion fuels. This report will present 24 different selective gas chromatographic detectors. These detectors, while not all directly applicable to the HRGC analysis of jet propulsion fuel, all show the concept of selective detection in gas chromatography. The applicability of these detectors to jet propulsion fuel analyses is determined from a comparison of their complexity and cost versus their effectiveness as high-resolution gas chromatographic detectors. Keywords: Ionization detectors, Fourier, Electron capture, Photoionization, Catalytic ionization, Infrared, Atomic absorption spectrometry, Ultraviolet.
Download or read book Detectors for Capillary Chromatography written by Herbert H. Hill (Jr.) and published by Wiley-Interscience. This book was released on 1992-10-30 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently there has been a great deal written about the benefits capillary chromatography offers in the area of separation and analysis. However, there is a need now to focus on the detection methods commonly used with capillary chromatography. Detectors for Capillary Chromatography presents the writings of 20 authorities who describe the unique features of each detector that are required for successful interfacing with capillary columns. Fused silica column technology has now advanced to the point where tremendous separation power is available. However, as these chapters show, without the ability to "see" the separated components, this high resolution is wasted. While it is true that the column is the heart of the chromatographic process, the detectors are the "eyes" that make the separation visible. A number of methods for "looking" at the results of chromatographic separations have been developed and each provides a different "view". To understand the information gained in high resolution chromatography, you must be able to interpret correctly the view provided by the detector. This book will provide you with the necessary insights into how you can accomplish that. The outstanding contributors to this book are all experts in the field. In many cases they are the researchers who originally developed the detector or have made major contributions to understanding its operation. This state-of-the-art text will be of immediate benefit to analytical chemists and physical chemists worKing with gas chromatography, who use this technique in environmental, industrial, or forensic investigations.

This book was released on 2012-12-06 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most universal and effective method for the analysis of complex multicomponent mixtures of volatile substances is gas chromatography. However, there are a number of limitations asso ciated with the classical variation of this technique which retard its development and the further expansion of its application: 1) the identification of the components of a complex mix ture of unknown composition is in itself a complex and difficult problem, unless the homologous series of the component to be identified is known; 2) the overlapping of chromatographic peaks for several compounds makes it difficult, and in a number of cases impossible, to carry out qualitative and quantitative analysis of these components, and leads to the necessity of using several columns of different polarities or to the use of columns with very high efficiency; 3) the direct analysis of unstable and nonvolatile compounds is impossible; 4) the difficulty of quantitative chromatographic analysis using thermal conductivity detectors increases with the necessity of determining individual response (calibration) factors; the insensitivity of the flame ionization detector to a number of substances (inorganic gases) leads to the necessity of introducing additional operations (prelimi nary concentration of trace components) in connection with thermal conductivity detectors. vii viii FOREWORD The directed use of chemical conversion of the compounds analyzed usually makes it possible to remove the limitations cited above.
