Comparison of CID and UV Photodissociation of Leucine Enkephaline Acquired at WSU.
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.

Why Oscilloscope Bandwidth Matters: A big part my New Year’s Resolution to improve my overall design process was better testing. Better testing is an important part of better and more intentional design, but it means having tools that you can trust and that can consistently give you the results you need. – http://www.adafruit.com/blog/?p=23753
