摘要
燃气中包括人工煤气、液化石油气和天然气,它们各自的组分、含量不同,存在着一定差异,又具有一定的共性,国家标准中要用多台气相色谱仪、不同的色谱分离柱进行分析。本文研究用两台气相色谱仪、两套色谱柱、两种定量方法、可以满足3种气体的分析方法,所建方法在两个实验室,通过多年的日常分析考验,结果证明分离效果和分析方法重复性好,精度高,既节约了人力、物力又节省了时间,同时也能满足3种气体分析和国家标准的要求。
Combustion gas can be divided into artificial coal gas, liquefied petroleum gas and natural gas. They have different components with different content, so their characters are not completely the same. But on the other hand, they still have some general character. More gas chromatography instruments and different chromatography separation column should be used to analyze the three kinds of gas in analysis process in the GB.Two sets of gas chromatography instruments, two sets of chromatography columns and two kinds of quantitative analysis methods which can be used to the analysis of the three kinds of gas have been emphasized in the thesis. After years＇ analysis and experiences in two laboratories, the method established has been proved that has perfect separate effect, repeatability and high accuracy, thus human resource and time are saved. The method also meets the requirements of the GB and analysis to the three kinds of gas.
