Gas chromatography continues to be one of the most widely used analytical techniques, since its applications today expand into fields such as biomarker research or metabolomics. This new practical textbook enables the reader to make full use of gas chromatography. Essential fundamentals and their implications for the practical work at the instrument are provided, as well as details on the instrumentation such as inlet systems, columns and detectors. Specialized techniques from all aspects of GC are introduced ranging from sample preparation, solvent-free injection techniques, and pyrolysis GC, to separation including fast GC and comprehensive GCxGC and finally detection, such as GC-MS and element-specific detection. Various fields of application such as enantiomer, food, flavor and fragrance analysis, physicochemical measurements, forensic toxicology, and clinical analysis are discussed as well as cutting-edge application in metabolomics is covered. About the Editors: Katja Dettmer-Wilde is Principal Investigator heading the mass spectrometry - metabolomics group at the Institute of Functional Genomics, University of Regensburg, Germany. She studied chemistry at the University of Leipzig and got her PhD with Werner Engewald working on the analysis of volatile organic compounds by GC-MS. Since her postdoctoral studies at the University of California Davis she has been focusing on hyphenated separation techniques in metabolomics. Werner Engewald is professor emeritus of the University of Leipzig, Germany. He is one of the leading gas chromatographers worldwide and has made substantial contributions towards the development of this technique. He regularly gives courses for GC users. He was awarded the Martin gold medal of the Chromatographic Society in 2002 and the Clemens-Winkler-Medal of the Division of Analytical Chemistry of the German Chemical Society in 2009.  .

This book represents an original research contribution in the area of aroma volatile biochemistry and the molecular analysis of basmati and non-basmati rice cultivars of India. It demonstrates the utility of headspace-solid phase micro extraction (HS-SPME) coupled with the gas chromatography-flame ionization detection (GC-FID) method, an approach that can help to understand not only the different volatiles contributing to pleasant aroma but also the volatile profile that generates the characteristic cultivar-specific aroma. In addition, the book provides detailed information on diversity, grain morphology, physico-chemical and cooking quality assessment, genetic diversity assessment and marker validation for important quality parameters. As such, it offers a valuable ready reference for agriculture scientists, biochemists, researchers and students involved in quality parameters of rice at the regional and global level.

Dit boek beschrijft de meest voorkomende methoden van chemische analyse en de bijbehorende meetprincipes. Deze uitgave is vooral bedoeld voor gebruik in de hogere jaren van de middelbare laboratoriumopleiding, maar is evengoed bruikbaar voor de meer ervaren laboratoriummedewerker ter verbreding van zijn of haar kennis. Veel aandacht is uitgegaan naar de leesbaarheid en het beeldmateriaal in kleur. Het boek wordt ondersteund door een website. Breed overzicht van de meest voorkomende chemische analysemethoden en technieken. Methoden en technieken zoals zuur/base titraties, oxidimetrie, argentometrie, UV-VIS spectrometrie, atomaire absorptiespectrometrie, infrarood-, massa- en kernmagnetische resonantie-spectrometrie, elektrochemische bepalingen en moderne scheidingsmethoden komen aan de orde. De auteurs besteden ook aandacht aan monstervoorbewerking en foutenanalyse. Het brede overzicht gaat wel ten koste van de diepgang. Van een aantal meetprincipes wordt een beknopte achtergrond gegeven; voor echt begrip heeft de lezer een uitvoeriger beschrijving nodig. Maar de klassieke analysemethoden zoals acidimetrie zijn prima beschreven. In het massaspectrometriehoofdstuk komt helaas een aantal fouten voor. Het boek is voorzien van oefenopgaven; de uitwerkingen zijn op www.mlochemie.nl te vinden. Bedoeld als studiemateriaal voor de hogere jaren van de middelbare laboratoriumopleiding; ook geschikt als naslagwerk voor de lezer die snel een overzicht wil krijgen van de chemische analyse.
