The performance of gas chromatography calibration requires specialized gas mixers to generate a test mobile phase with desirable concentrations. This is dependent upon the application area, but typical gas chromatography studies require mass accuracy levels to the parts per million (ppm) and parts per billion (ppb) range In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed. Because the different constituents of the mixture. Application of Gas Chromatograph. 1.
