利用氧化还原反应检测燃料氢气中的杂质

Analysis of Impurities in the Fuel Hydrogen by Redox Reaction

检测燃料氢气的杂质时,使燃料氢气通过氧化还原反应装置。其余杂质由载气载入色谱分离系统进行有效分离后检测。该方法彻底除去氢和氧,消除了分析中主成分对其他杂质的干扰。测量重复性小于3%,测量范围可达0.055~5000(μL/L),且无需采用中心切割方法。

For the detection of impurities in the fuel hydrogen,the fuel hydrogen passed through the redox reaction device.Then the other impurities in the fuel hydrogen were loaded into chromatographic separation system by carrier gas for effective separation and detection.The hydrogen and oxygen are removed in the reaction process,which effectively avoids the interference of analysis because of the absence of hydrogen and oxygen.The repeatability of measurement is less than 3%,the measurement range can reach 0.055~5000(μL/L),and the central cutting method is not needed.
