IMS – Ion Trap Equipped with UV Photofragmentation

In early 2015 the research group is pleased to bring the next generation ion mobility-ion trap system online.  This system is equipped with two ion gates which allows the speed of the IMS to be effectively coupled to the slow scan speeds of traditional ion trapping experiments.  Though not as fast as tradition IMS-TOF configurations, this experimental setup does allow multiple stages of CID and alternative modes of fragmentation such as UV and IRMPD.  Another unique feature of this IMS system is that it can obtain IMS spectra using a standard Faraday plate and/or the LTQ.

The ExcellIMS Dual Gate System smoothly mates to the LTQ.

Though a little difficult to see the IMS tube actually uses a square drift tube design with a nice set of BN gates.
