Specificity is obtained by virtue of a separation process rather than detection. The separation is hence accomplished by partitioning the sample between the gas and a thin layer of a nonvolatile liquid held on a solid support. A gas chromatographic system is comprised of six major components: Once the gas chromatograph detector is contaminated, the sensitivity is significantly reduced or the noise is increased and the dots are not ignited. The inlet, the column oven, and the detector.
Other specialty gases used in association with gc are gas mixtures to calibrate the detector in order to ensure accurate measurement, or zero gases to set a zero reading on the detector. A gas chromatograph consists of a flowing mobile phase, an injection port, a separation column containing the stationary phase, and a detector.
