Gas chromatography is analytical technique used to separate volatile compounds and analyze their concentrations. It involves vaporization of sample mixture, carriage of analytes through a long capillary column by inert carrier gas, and detection of analytes individually based on their interactions with column components. Advantages of gas chromatography include accurate quantification down to parts-per-billion or even lower levels, minimal sample preparation requirements, ability to analyze ... Read more

Gas chromatography (GC) is an analytical chemistry technique used to separate and analyze compounds that can be vaporized without decomposition. Separation is a function of volatility and polarity. Less volatile compounds elute later than more volatile compounds with similar polarity. Compounds that interact differently with the stationary phase also separate better. Different stationary phases ... Read more
