Field asymmetric time of flight ion mobility spectrometry

Year:  2016
Funding:  This work has been supported by the German Federal Ministry of Economics and Technology (BMWi), under the Grant KF3238301NT3 upon decision of the German Bundestag

In this work, we are developing a new concept for miniaturized and low cost ion mobility spectrometers (IMS) manufactured from printed circuit boards (PCB). The goal is a system which is small and cheap, but provides the analytical power of high end systems. To achieve this, we try to combine the advantages of time of flight IMS (TOF-IMS) and field asymmetric IMS (FAIMS) by inserting a chamber with an alternating electrical field into the drift tube of a PCB based TOF-IMS.
