At the beginning of this dissertation, the history of gas chromatography devices and a brief description of how these devices work is discussed. In the following, the different parts and components of this device and also description of how this device will work are described. Similarly, types of calibration methods in this device, which include internal standard, external standard and also additional standard according to the necessary instructions will described. Other methods that are described can be linear calibration using average calibration as well as linear calibration using minimum that mentioned the regression of squares. In the research method section of this dissertation, the methods in the laboratory are examined. Internal standard, external standard, and additional laboratory methods have been studied in the laboratory, and methods of testing and their results are described. Argued other issues that can be considered and analyzed. For example, problems that may arise for a device that demonstrates the need for calibration, such as scaling, widening, and noise chromatography, and solutions to fix them. In the data analysis section, the advantages and disadvantages of the methods and experiments performed in the research method section are examined, and the internal standard and external standard methods are compared with each other, also the additional standard method is discussed. In addition, degree of uncertainty and accuracy of gas chromatography devices during natural gas analysis examined. Finally, some samples for each calibration method examined and also showed their results.
