2.1.6 Ion Optics After the ions have been successfully extracted from the interface region, they are directed into the main vacuum chamber by a series of electrostatic lens, called ion optics. The operating vacuum in this region is maintained at about 10−3 Torr with a turbomolecular pump ...
The reaction with the strong Lewis acid SbF5 can be shown as (16.57)SbF5 + SF4 → F4S:SbF5 As a result of sulfur not being restricted to a maximum of 8 or 10 electrons in the valence shell, SF4 can also act as an electron pair acceptor, so it can behave as a Lewis acid also. ...
