  • Page 19: Working Principle And Internal Gas Flow

    Working Principle and Internal Gas Flow The schematics below show the main elements of the gas flow system of the device. The system consists of a gas chromatograph (GC) using a capillary column coupled to an ion mobility spectrometer (IMS).

  • Page 20: Figure 2: Flow-Chart

    EPC1. The carrier gas flow to the column is controlled by EPC2. Carrier gas and drift gas leave the device through the Gas Out outlet at the rear side of the device, which should be connected to an appropriate waste gas ventilation system.
  • Page 21 The sample gas or test gas is sucked in by pump P via Samplegas In and Testgas In at the rear side of the housing from the bypassing gas. The minimum bypass flow is 200 ml/min. The sample gas or test gas is carried via the 6-Port-Valve to the gas chromatographic capillary column GC from where it elutes into the ion mobility spectrometer IMS.
