Book Description
Trace Analysis, Volume 2 is devoted to critical discussions of selected topics in organic and inorganic analytical chemistry including instrumentation, techniques, and applications to the detection, identification, and quantitation of trace quantities of substances in a large variety of sample materials. The volume presents expositions of selected topics on trace analysis such as vitamin analysis in foods and tissues; liquid chromatography - mass spectrometry with emphasis on approaches to interfacing; approaches to the isolation and concentration of trace organics from aqueous samples; and the advantages of unmodified silica gel for the chromatographic separation of polar substances. The book will be highly useful to both organic and inorganic chemists.

Book Description
The Commission of the European Communities presents with this volume the proceedings and the conclusions of the second European Symposium on the analysis of organic micropollutants in water. This symposium has been organized within the framework of the Concerted Action "Analysis of Organic Micropollutants in Water". This research programme is jointly implemented by the European Communities and Norway, Portugal, Spain, Sweden, Switzerland and Yugoslavia within the framework of a COST (Cooperation Scientifique et Technique) agreement. The project, also known as COST Project 64b bis, aims at coordinating all relevant research in this field in the participating countries. An effort is made to improve methods and techniques for the identification and quantitative determination of organic compounds present in all types of water. The symposium permitted to review the results achieved during the past three years of research in the following areas: - Sampling and sample treatment - Gas-chromatography Separation of non-volatile compounds, in particular high performance liquid chromatography (HPLC) - Mass-spectrometry - Data processing - Specific analytical problems, in particular the analysis of organic halogens and phenolic compounds. The volume gives a rather complete overview of the activities in this field in Europe. We are confident that it constitutes a valuable contribution to solving the important problems posed by the huge number of already identified or yet unknown organic pollutants in water. The Commission of the European Communities wishes to express their sincere thanks to the co-organizers, the National Board for Science and Technology, Dublin and An Foras Forbartha, Dublin.

Book Description
With the second volume in this senes we have continued the theme of Volume 1 and expanded more generally into separation and continuous flow techniques. The first chapter gives an account on flow injection analysis. Thi~ technique has gained considerable interest in the recent past and offers many facets of the use of chemistry in automated analysis procedures. One of these facets is certainly also the use of ion-pairing reactions, and we have been fortunate to get two well-known experts to treat this subject. The use of ion-pairing techniques is being discussed from a batch extraction (sample handling) point of view as well as for flow injection and chromato graphic purposes. Immobilized enzymes are another area of major attention and their multidirectional use in analytical chemistry is illuminated in Chapter 3 with special emphasis on their use in connection with liquid chromatography. Needless to say, similar techniques have also found their way into con tinuous-flow methodology (Auto-Analyzers) and many of the aspects dis cussed in Chapter 3 are adaptable to this end. The need and recent urgency for separation of optical isomers in many areas, particularly pharmaceutical and clinical analysis, has spurred a flurry of activity in this special section of chromatography. The current status of the field of optical isomer separation is competently reviewed in Chapter 4. Again this is a typical area wherein it is the proper use of chemistry that finally delivers a solution. The last two chapters deal with precolumn or prechromatographic derivatization techniques.

Book Description
Despite the development of innovative new analytical techniques for biological trace element research, today's trace element investigators face formidable obstacles to obtaining reliable data. This complete reference identifies and assesses the challenges the analyst encounters at each stage of an analysis, and discusses the effects of various techniques on the sample. Three internationally recognized scientists and authors consider the effects of the numerous collection, storage, and sample preparatory techniques used in sample analysis. Proper analytical quality control, including such critical factors as sampling and sample preparation, specimen preservation and storage, and ashing, is examined. The book also looks at sample preparation methods unique to various instruments and speciation chemistry issues, and examines the link between chemical analysis and specimen banking. A previously unrecognized source of error, presampling factors, is also discussed.
