1. Resource Description

   A quadrupole/travelling wave ion mobility (TWIM)/time-of-flight mass spectrometer. Ion mobility enables gas-phase ions to be separated by their size, shape, and charge. This affords a dimension of separation orthogonal to the standard m/z analysis. The instrument has been modified with a custom surface-induced dissociation (SID) device which can be placed before the IM region (SID-IM), after the IM region (IM-SID), or on either side of the IM cell to allow for SID-IM-SID. In addition, a linear field ion mobility cell can be installed and used to make direct collision cross section measurements without the need for calibration, as is necessary for TWIMS measurements. This instrument is mainly used for studies of large protein complexes.
