Gas Chromatography
Gas chromatography (GC) is one of the most important types of chromatography used in analytical chemistry for separating and analyzing chemical organic compounds. Today, gas chromatography is one of the most widespread investigation methods of instrumental analysis. This technique is used in the laboratories of chemical, petrochemical, and pharmaceutical industries, in research institutes, and also in clinical, environmental, and food and beverage analysis. This book is the outcome of contributions by experts in the field of gas chromatography and includes a short history of gas chromatography, an overview of derivatization methods and sample preparation techniques, a comprehensive study on pyrazole mass spectrometric fragmentation, and a GC/MS/MS method for the determination and quantification of pesticide residues in grape samples.

Detection-Oriented Derivatization Techniques in Liquid Chromatography
This book covers the principles, kinetics, and applications of derivatization reactions in liquid chromatography. It emphasizes detection-oriented derivatization procedures that can be used to enhance to detectability of a wide variety of solutes using absorbance and fluorescence detection.
Chemical Derivatization in Analytical Chemistry
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 en...
Chemical Derivatization in Analytical Chemistry
The first volume in this series is devoted to derivatization techniques in chromatography, for very obvious reasons. In gas chromatography (GC) chemical derivatization as an aid to expand the usefulness of the technique has been known for more than a decade and has become an established approach. The first chapter deals to a great extent with derivatization for the purpose of making compounds amenable to Gc. Although the discussion concentrates on pesticides, some generally valid conclusions can be drawn from this chapter. Chemistry will not be limited to the separation-it can also have a pronounced impact on the sample cleanup, another topic cov ered in Chapter 1. Since the introduction of coupled GC-mass spectroscopy (GC-MS), a very powerful tool, derivatization techniques have taken still another di rection-taking into consideration chromatographic as well as mass spec trometric improvement of the compounds of interest. Cyclic boronates are discussed as derivatization reagents for this purpose in the second chapter.
Sample Preparation in Chromatography
Sample preparation is an essential step in many analyses. This book approaches the topic of sample preparation in chromatography in a methodical way, viewing it as a logical connection between sample collection and analytical chromatography. Providing a guide for choosing the appropriate sample preparation for a given analysis, this book describes various ways to process the sample, explaining the principle, discussing the advantages and disadvantages, describing the applicability to different types of samples, and showing the fitness to specific chromatographic determinations. The first part of the book contains an overview of sample preparation showing its relation to sample collection and...
