Development of Multi-stage Ion Trap Ion Mobility System and Optical Detection of Charged Particles
We have been developing "Ion Trap Mobility Measurement System". By using the system fine particles are trapped for more than 2 hours with monitoring the structural changes. However, the detection sensitivity and flexibility are limited by the image detection system. Here we show a newly developed multi-stage ion trap mobility measurement system with optical detection. The system consists of a stacked ring ion guide type multi-stage ion trap, optical fibers. The charged particle was detected by photo detectors to monitor its movement and to elucidate its mobility. The flexibility and the possibility of the multi-stage ion trap ion mobility system with multiple-position optical detection will be discussed.
