Book Mass Spectrometry of Priority Pollutants

Download or read book Mass Spectrometry of Priority Pollutants written by Brian Middleditch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the list of organic priority pollutants was first published, many mass spec troscopists went scrambling to their reference books. GC-MS was mandated for the analysis of 114 compounds, yet the spectra of many of them, if they had been recorded at all, were scattered throughout the literature. Moreover, it soon became apparent that, even if a sufficient number of instruments could be made available to undertake the task of monitoring 114 substances in the effluents of 21 categories of industry, the personnel could not be trained to perform the analyses and interpret the results. The solution to this problem has been the development of highly automated mass spectrometers which can be operated by personnel without the traditional research training. This book is for the new breed of mass spectroscopist who is not interested in the esoteric details of mass spectral fragmentation, but who merely wishes to identify specific pollutants in effluents. Our inclusion of com prehensive lists of synonyms and bibliographic data should make the book of even greater value to the reader who is not too familiar with the idiosyncrasies of chemical nomenclature and the scientific literature. The experienced mass spectroscopist should also benefit from having all of the data collected together in one volume. This is a book to be used, rather than deposited in a library distant from the laboratory: we would hope that it will fmd a place on top of every mass spectrometer used for the analysis of priority pollutants.

Book Mass Spectrometry in Environmental Sciences

Download or read book Mass Spectrometry in Environmental Sciences written by F.W. Karasek and published by Springer. This book was released on 1985-02-28 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past ten years a variety of methods involving mass spectrom etry have been developed for the analysis of environmentally important compounds. Much has been accomplished in that period to solve some of the important problems in the field. Growth of this methodology and its accomplishments has reached the point where an individual scientist can no longer have an in-depth knowledge of all the areas involved. We have attempted to provide this in-depth picture to those scientists con cerned by having the important topics treated by experts in the subject matter. In order to provide all the relevant material in one volume we begin with the general topics which provide the basic background material necessary to understand the techniques discussed in the in-depth topics. These general chapters are kept brief, containing only the essentials needed by the working scientist to deal with the practical applications. References in these chapters are chosen to permit a more complete study of each chapter. The concept for this book was developed during the activities of two of the editors under a NATO travel grant. These editors gratefully acknowledge this support which made the initial planning of this book possible. The editors would like to thank the individual authors of each chap ter for their cooperation and generously giving of their time for this project.

Book Application of Deuterated Organics as Internal Standards in Volatile Organic Analysis from Drinking Water and Wastewater by Computerized Gas Chromatography  Mass Spectrometry

Download or read book Application of Deuterated Organics as Internal Standards in Volatile Organic Analysis from Drinking Water and Wastewater by Computerized Gas Chromatography Mass Spectrometry written by RF. Devine and published by . This book was released on 1979 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method utilizing computerized gas chromatography-mass spectrometry (GC-MS) is presented for qualitative and quantitative determination of volatile organics in drinking waters, natural waters, or industrial effluent waters. It is based on the addition of deuterated internal standard, 1,2-dichlorethane-d4, to an appropriate-sized portion of sample and use of the Bellar-Lichtenberg method of purge-trap-desorb into determinative instrument. Method validation consisted of analyzing volatile priority pollutants at 2, 10, 50, 100, and 200 ppb with internal standard at 20 ppb in each of seven replicate analysis at each dose. Comparison of relative standard deviations (RSD) of internal and external standard methods of GC-MS analysis revealed no significant differences. This study also yielded valuable information concerning repeatability, reproducibility, stability of internal standard, linear dynamic range of GC-MS, and RSD variation with different area regenerations of diagnostic atomic mass units. Pollutant identification is based on retention time and total mass spectral comparison with authentic compound. Quantitation is based on measurement of the areas of retrieved diagnostic atomic mass unit regeneration of contaminant and internal standard. Using response factors determined from analysis of standard mixtures containing compounds of interest and internal standard, and the known mass of internal standard, the concentration is calculated. Lower detection limit for the volatile priority pollutants is approximately 1 ?g/litre. This method has detected several volatiles that are not Environmental Protection Agency priority pollutants.

Book IDENTIFICATION OF VOLATILE ORGANIC COMPOUNDS IN WATER BY GAS CHROMATOGRAPHY MASS SPECTROMETRY USING PURGE AND TRAP SAMPLE CONCENTRATION AND INTRODUCTION

Download or read book IDENTIFICATION OF VOLATILE ORGANIC COMPOUNDS IN WATER BY GAS CHROMATOGRAPHY MASS SPECTROMETRY USING PURGE AND TRAP SAMPLE CONCENTRATION AND INTRODUCTION written by Bruce T. Heitke and published by . This book was released on 1983 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation was to evaluate the purge and trap methods and the Hewlett-Packard model 7675A purge-and-trap sampler for the identification of volatile compounds in water by gas chromatography/mass spectrometry. The manner in which this instrument accomplished the transfer of volatile components in water to the chromatographic column is thoroughly described. Guidance is given to the analyst in the specification of operating parameters for the optimization of this transfer. The instrument was evaluated with both packed and capillary columns by using: (1) the volatile organics among Environmental Protection Agency's (EPA's) priority pollutants and (2) ground water samples from Rocky Mountain Arsenal. The Hewlett-Packard model 7675A purge-and-trap sampler proved to be adequate for identifying removable organic compounds in water at concentrations of 4 ng/ml (4 ppb) provided that packed-column chromatography is sufficient to resolve the components. This instrument is not suitable for capillary column applications.
