Abstract
Currently, High Kinetic Energy Ion Mobility Spectrometers (HiKE-IMS) are under investigation regarding trace gas detection in field applications. Despite their low operating pressures between 20 and 60 mbar, previously reported limits of detection for compounds like benzene are in the single digit ppbV-range [1]. However, even lower detection limits for a broad range of substances are required. To achieve this objective, we experiment with operating pressure and electric field strength to further improve the limits of detection of HiKE-IMS.
