description: Preparative mass spectrometry is a gas-phase ion deposition
 technique aimed at deposition of monodisperse ion beams on a surface.  This is
 accomplished through the implementation of a soft-landing ion mobility system
 which allows for high ion flux of conformationally selected ion packets.  The
 soft-landing ion mobility system has been applied to a number of unique
 chemical problems including the deposition of insulators on graphene, the
 preparation of reusable surface enhanced Raman spectroscopic substrates, and
 the deposition of uranium nanoparticles.  Soft-landing ion mobility provided a
 platform for the quick deposition of usable amounts of materials, which is the
 major objective of preparative mass spectrometry.  Soft-landing ion mobility
 is unique when compared to other preparative mass spectrometric techniques in
 that the ion packets are conformationally separated, not separated on mass to
 charge ratio.  This provides orthogonal complementary data to traditional mass
 spectrometric techniques and allows for the study of conformationally
 monodisperse surfaces.  The diversity of problems that have been and continued
 to be explored with soft-landing ion mobility highlight the utility of the
 technique as a novel tool for the study of multiple ion/surface interactions.
