Overview

Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analysing compounds that can be vaporized without decomposition. In gas chromatography, the components of a sample are dissolved in a solvent and vaporized so as to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase. Gas chromatography is in principle similar to column chromatography, but has several notable differences. as chromatography is also similar to fractional distillation, since both processes separate the components of a mixture primarily based on boiling point (or vapour pressure) differences. The mobile phase is a chemically inert gas that serves to carry the molecules of the analyte through the heated column. Gas chromatography is one of the sole forms of chromatography that does not utilize the mobile phase for interacting with the analyte. The stationary phase is either a solid adsorbant, termed gas-solid chromatography (GSC), or a liquid on an inert support, termed gas-liquid chromatography (GLC). In organic chemistry, liquid-solid column chromatography is frequently used to separate organic compounds in solution. Among the various types of gas chromatography, gas-liquid chromatography is the method most commonly used to separate organic compounds. The combination of gas chromatography and mass spectrometry is a vital tool in the identification of molecules. A typical gas chromatography comprises an injection port, a column, carrier gas flow control equipment, ovens and heaters for maintaining temperatures of the injection port and the column, an integrator chart recorder and a detector. The book, Advanced Gas Chromatography, is intended to cover numerous facets of applications ranging from basic biological, biomedical applications to industrial applications. The book analyse new developments in chromatographic columns, micro extraction techniques, derivatisation techniques and pyrolysis techniques. The book also focuses on various features of basic chromatography techniques and is appropriate for both young and advanced chromatographers. It includes some new developments in chromatography. This book is an invaluable tool for chemists as well as non-chemists employed in gas chromatography.
