Ion Mobility Spectrometer with a Resolving Power of R = 100

For the analysis of gas mixtures at atmospheric pressure we developed a compact drift tube ion mobility spectrometer (IMS) with a length of about 100 mm and an outer diameter of 30 mm. Furthermore, the resolving power belongs to R=100. The IMS can be operated in a temperature range between room temperature and 100°C. Due to the institute’s own machine shop it is also possible to rapidly modify the IMS for many applications. For example, the ionization region can modified, thus several ionization sources can be compared. Of course, the detection region can be modified to adapt the IMS to a mass spectrometer.
