摘要
研究了在双气路热导池上使用双载气的适宜条件,建立双柱双载气TCD的气相色谱法,应用于动火分析中可燃气体H2和CO的同时测定。方法检出限分别为H20.001 5%,CO 0.019%,测定结果的相对标准偏差分别为1.2%,2.1%。
The gas chromatography was established by using double column and double carrier gas TCD after studying the application conditions of double carrier gases in double gas circuit thermal conductivity cell,and will be applied to detect the content of flammable gases,such as H2 and CO before starting hot work.Method detection limits are 0.0015% for H2 and 0.019% for CO,and the relative standard deviations are 1.2% and 2.1% respectively.
