Natural gas is a green,efficient and clean energy,which is complementary to renewable energy.Fully under-standing the composition of natural gas can promote the utilization of natural gas.Taking natural gas reference material as the object,the influence of chromatographic instrument conditions on natural gas analysis was studied,including column type,valve cutting time,column box temperature and so on.A good analysis method was established,and the retention time of natural gas components was determined by external standard method.Using this gas chromatography to determine natural gas components has the characteristics of good repeatability,high accuracy and short analysis time,which can pro-vide important reference for analyzing and detecting natural gas components and is of great significance to the quality control of natural gas production and transportation.
