    Gas Chromatography - an overview | ScienceDirect Topics

    Gas chromatography (GC) is a separation technique capable of separating highly complex mixtures based primarily upon differences of boiling point/ vapor pressure and of polarity. Even though chromatography was invented at the beginning of the twentieth century and Martin and Synge did not see any reason why the mobile phase should not be a gas in their 1941 publication, GC was not …

    Gas Chromatography - What It Is and How It Works

    Jan 27, 2019· Gas chromatography (GC) is an analytical technique used to separate and analyze samples that can be vaporized without thermal decomposition.Sometimes gas chromatography is known as gas-liquid partition chromatography (GLPC) or vapor-phase chromatography (VPC).

    Gas Chromatography - Chemistry LibreTexts

    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).

    Sample Preparation Techniques for Gas Chromatography .

    In gas chromatography (GC), the sample is vaporized and injected onto the head of a chromatographic column. Elution is brought about by the flow of an inert gaseous mobile phase such as helium, argon, nitrogen, carbon dioxide, and hydrogen. In GC, the mobile phase does not interact with molecules of the analyte, and it only transports the analyte through the column.
