Natural gas analysis by GCs play an important role in gas trade. This article describes the influence of natural gas accuracy by GCs on the caloric value and hydrocarbon dew point calculated from gas composition, and natural gas standards are a kind of measuring instrument to guarantee the accuracy of natural gas analysis results. There is a big difference in the accuracy class of natural gas standards in our country when compared with the international advanced levels. This article gives the "best practices for gas preparation" proposed in the research project of "Preparation method for chromatographic natural gas calibration standards" undertaken by Southwest Research Institute (USA), and put forward relative recommendations.
