摘　　要：本研究采用带有脉冲放电氦离子检测器的气相色谱仪,并结合阀切割技术,分别利用N柱、氨柱、FFAP毛细柱分析氢气中甲醛、氨气及甲酸杂质,建立了一种高纯氢中甲醛、甲酸及氨气杂质的气相色谱快速检测方法。结果表明,该分析方法具有较好的重复性。此法可应用于燃料电池氢气中所要求的几种对燃料电池性能有重大影响的杂质的快速检测。A rapid method for the determination of formaldehyde, formic acid and ammonia in high purity hydrogen was developed by gas chromatography with pulse discharge helium ion detector and valve cutting technology. The results show that the method has good repeatability. This method can be applie d to the rapid detection of several impurities required in the national standard of hydrogen for fuel cells.
