Ultra high resolution ion mobility spectrometry
|Förderung durch:||This research is founded by the German Research Foundation (DFG)|
The aim of this research is the development of an ion mobility spectrometer with a resolving power above 300 and limits of detection in the pptv range for measurement times of less than a second. Furthermore, the performance using various non-radioactive ion sources such as X-ray and UV sources, electrospray ionization as well as non-radioactive electron emitters is being investigated. With a resolving power of 250 even for small, single-charged ions, the current setup is at the moment the highest resolving ion mobility spectrometer worldwide and the first device to separate isotopologues.
