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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Analytical Methods for Pesticides and Plant Growth Regulators, Volume IX: Spectroscopic Methods of Analysis covers the progress in spectroscopic methods for pesticide analysis. The book discusses the use of high-pressure liquid chromatography coupled to mass spectrometry for the analysis of heat-labile compounds; and the applications of nuclear magnetic resonance spectroscopy and related techniques, and visible and ultraviolet spectrophotometry. The text also describes the applications of spectrophotofluorometry, infrared spectrometry, and a collection of infrared spectra of important pesticides. Toxicologists, chemists, and people working in pesticide laboratories will find the book invaluable.
