阀切换在化肥分析专用多通道全自动气相色谱仪中的应用

Application of Valve Switching in Multichannel Auto Chromatograph Used Specially for Chemical Fertilizer Analysis

    摘要
  • 摘要: 阐述了阀切换在化肥专用多通道气相色谱仪中应用的原理、硬件、软件、流程和色谱图.现场使用表明:利用微机控制阀切换进行多点采样进样分析,能减少手动进样与人工处理数据的误差.

     

    Abstract: The principle, hardware, software, gas system and chromatogram of multichannel autochromatograph using switching valve controled by computer are reported. The result shows that this technology can reduce errors from the hand injection and manual data processing.
