The only reference to provide both current and thorough coverage ofthis important analytical technique Static headspace-gas chromatography (HS-GC) is an indispensabletechnique for analyzing volatile organic compounds, enabling theanalyst to assay a variety of sample matrices while avoiding thecostly and time-consuming preparation involved with traditionalGC. Static Headspace-Gas Chromatography: Theory and Practice has longbeen the only reference to provide in-depth coverage of this methodof analysis. The Second Edition has been thoroughly updated toreflect the most recent developments and practices, and alsoincludes coverage of solid-phase microextraction (SPME) and thepurge-and-trap technique. Chapters cover: * Principles of static and dynamic headspace analysis, includingthe evolution of HS-GC methods and regulatory methods using staticHS-GC * Basic theory of headspace analysis-physicochemical relationships,sensitivity, and the principles of multiple headspaceextraction * HS-GC techniques-vials, cleaning, caps, sample volume,enrichment, and cryogenic techniques * Sample handling * Cryogenic HS-GC * Method development in HS-GC * Nonequilibrium static headspace analysis * Determination of physicochemical functions such as vaporpressures, activity coefficients, and more Comprehensive and focused, Static Headspace-Gas Chromatography,Second Edition provides an excellent resource to help the readerachieve optimal chromatographic results. Practical examples withoriginal data help readers to master determinations in a widevariety of areas, such as forensic, environmental, pharmaceutical,and industrial applications.

Plants and plant-derived compounds and drugs are becoming moreand more popular with increasing numbers of scientists researchingplant analysis. The quality control of herbal drugs is alsobecoming essential to avoid severe health problems, and in thefuture many more new drugs will be developed from plantsources. This three-volume Handbook, featuring 47 detailed review articles,is unique as it deals with chemical and biological methodologiesfor plant analysis. It presents the most important and mostaccurate methods which are available for plant analysis. This comprehensive work is divided into six sections asfollows: Sample preparation and identification – discussingplant selection and collection, followed by extraction and samplepreparation methodologies. Extraction and sample preparation methodologies Instrumentation for chemical analysis - severalinstrumentations for chemical plant analysis are presented with anemphasis on hyphenated techniques, e.g. the coupling between HPLCand mass spectroscometry, and HPLC with NMR. Strategies for selective classes of compounds –coverage of the most interesting classes of compounds such aspolysaccharides, saponins, cardiotonic glycosides, alkaloids,terpenoids, lipids, volatile compounds and polyphenols (flavonoids, xanthones, coumarins, naphthoquinones, anthraquinones,proanthocyanidins, etc.). Biological Analysis - includes phenotyping, DNA barcodingtechniques, transcriptome analysis , microarray, metabolomics andproteomics. Drugs from Plants – covers the screening of plantextracts and strategies for the quick discovery of novelbioactive natural products. Safety assessment of herbal drugs ishighly dependent on outstanding chromatographic and spectroscopicmethods which are also featured here. This Handbook introduces to scientists involved in plant studiesthe current knowledge of methodologies in various fields ofchemically- and biochemically-related topics in plantresearch.
