【摘要】 本文提出了一种为分析测定CO₂,O₂,N₂,SO₂,CO₂,CH₄,H₂S以及NO的气相色谱系统。通过对组分间分离度与温度等条件之间关系的考察确定最佳色谱操作参数。设计了自动转换信号极性的电子线路,使方法具有快速、自动、操作简单等特点。更多还原

【Abstract】 A gas chromatographic system is described for the analysis of carbon monoxide, oxygen, nitrogen, sulfur dioxide, carbon dioxide, methane, hydrogen sulfide and nitrogen oxide from a single injection. The system consists of three columns in series with an identical (105℃). Both cells of the detector (TCD) are used alternatively as reference and measuring cells. The correlation between resolution and temperature was obtained. An electronic system for automatic switching signal polarity was designed.更多还原
