  • Page 29: 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 30 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 31 BreathSpec® – 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 32 Therefore G.A.S. -according to application- equips its IMS systems with gas chromatographic (GC) columns. The volatile compounds of samples under testing are pre-separated in time by a GC column. The discrete compounds are consecutively fed into the IMS ionization chamber, so that analyte and/or ion interactions are avoided.

  • Page 33: Purpose Of The Device

    The BreathSpec® can be operated in negative or positive drift voltage mode. The reactant ion peaks (RIPs) and analyte ion peaks (AIPs) in the positive drift voltage mode will be displayed as maxima in the spectra.
  • Page 34 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 BreathSpec® or – when activated – in a shared net-work folder. Stored measurement files can further be copied to a connected USB volume.

    (EPC1). The carrier gas for the column is supplied using a second electronic pressure control unit (EPC2). Both gases (carrier and drift gas) leave the device at the gas out and goes back again into the circular gas flow unit (Gas In). INFORMATION! To ensure correct measurements it is necessary to connect the supplied exhaust tube (Sample gas out).
  • Page 36 “Fill Loop”. In this position the sample gas from the Sample In socket is directly routed to the Sample Out socket. For routing the sample gas in the loop to the GC-Column and to the IMS, the 6-port- valve is switched to the second position. The carrier gas now transports the sample gas into the loop and further to the GC-Column, where the substances in the sample gas are separated by time.
