摘　　要：本文采用光离子化和热导池两个检测器串联,以5A钙型分子筛填充柱与Chromesorb 104+2％KOH填充柱并联方式,成功地定量分离分析了N2,O2,NO或NO_2,N_2O和NH_3的混合气体。The quantitative separation and determination of nitrogen, oxygen, nitric oxide (or nitric dioxide), nitrous oxide and ammonia in gaseous mixture are successfully carried out by using a gas chromatographic system equipped with photo-ionization detector and a thermal conductivity detector. Two columns in parallel packed with 5 molecular sieves and Chromsorb 104 + 2％ KOH are required.
