1. transmission line system between a kind of gas chromatography-mass spectrum for dioxin on-line checking, including for connecting gas-chromatographyThe docking pipeline of instrument and time of-flight mass spectrometer;

  • Characterized in that, the chromatographic column inside gas chromatograph has extension, this prolongsSection is stretched to be set in the docking pipeline;

    The end of docking pipeline is connected to pulse valve by cutting ferrule bilateral and reducer union, and rightConnected inside adapter Lu Buyu pulse valves;

    The extension of chromatographic column is passed through after pulse valve, with time of-flight mass spectrometer internal cavitiesConnection;

    Pulse valve is installed on time of-flight mass spectrometer, and is realized synchronously according to the laser pulse frequency of time of-flight mass spectrometerOpening and closing.
