The Production, Verification and Value Determination for Reference Gas Mixture(RGM) Used for Natural Gas Analysis

Along with the RGM is popularly used all over the world, it's production, verification and value determination have become a key point for keeping uniform of measuring system globally. Since GB/T 22723-2008 is issued, the research and production of high-accuracy RGM for natural gas analysis are widely paid close attention. Because the production, verification and value determination for these kinds of RGM are relatively complicated, the regulations of GB/T 5274-2008 and GB/T 5274-2008 15000 must be executed strictly. Based on examples, some notable problems for producing RGM of natural gas analysis are discussed in this article.
