Gas Chromatograph 1
Gas Chromatograph 1 : A chromatograph that physically separates components of a mixture and measures them individually with a detector whose signal is processed. A chromatograph consists of the following main parts: an introduction unit, a separation unit and a detector. The separation unit consists of one or more chromatographic columns through which carrier gas flows and into which samples are introduced. Under defined and controlled operating conditions, components can be qualitatively identified by their retention time, and quantitatively measured by comparing their detector response to that of the same or a similar component in a calibration mixture
