  • Page 21: Introduction

    Compared to other techniques e.g. TOF-MS, ions travel at atmospheric pressure versus a flow of inert drift gas. The drift time of each substance is determined by its ion mass and geometric structure, as slowing collisions with the drift gas molecules are more frequent for sterically demanding structures.
  • Page 22 10.6eV UV-lamp or soft chemical-ionization initiated by a low-radiation tritium (H3) source (below exemption limits of EURATOM). While the first directly produces positive ions, the latter generates reactant ions with the gas atmosphere by a cascade of reactions following the collision of a fast electron emitted from the β-radiator H3.
  • Page 23 GC-IMS – User Manual Figure 3: IMS Predominant Ionization (positive polarization) The above figure exemplarily shows typical IMS spectra without analyte and with analyte. The RIP is formed as a sharp signal proving the cleanliness of the system and at a specific position that is used as internal standard. The spectrum containing analytes shows a decreased RIP, while new (analyte) peaks are correspondingly formed.
  • Page 24 Furthermore a competition of analytes on the reactant ions is excluded, enhancing the sensitivity of the system for individual compounds. The GC-IMS setup enables a twofold separation of analyte mixtures and the detection by the IMS electrometer. Since the IMS measurements are extremely fast (30ms / spectrum) a continuous and high-resolution recording of analyte signals is provided.

    Measurement data can also be acquired in a manual way using the “Recording” mode. Acquired measurement data are stored in measurement files either on the internal storage volume of the GC-IMS or – when activated – in a shared net-work folder. Stored measurement files can further be copied to a connected USB volume.
