Ion mobility spectrometry coupled to chip-based electrochromatography

In this cooperation project with the group of Professor Belder from the Leipzig University a chip electrochromatography (ChEC) is coupled to a compact electrospray ion mobility spectrometer (ESI-IMS) from our group. The aim of this work is to characterize ESI-IMS as detector for chip based separation techniques. Furthermore, secondary ionization with APPI and APCI sources is implemented in the desolvation region of the ESI-IMS to enable the detection of compounds that cannot be ionized by electrospray.
