Title: Ion Soft Landing for Structural Analysis and Material Preparation

Abstract:

Mass spectrometry is an analytical technique that is becoming ubiquitous across many fields of science. Current applications of mass spectrometry apply it solely analytically, by depositing ions onto detectors with no way of recovery. However, the electric and magnetic fields employed to manipulate ions in the gas phase are not destructive by nature. By taking advantage of this fact, ion soft landing is a relatively new technique that attempts to deposit ions onto a surface where they can be recovered. This can be used in both an analytical and preparatory way. Analytically it can be used to probe structural characteristics for peptides and proteins and surface characteristics on electrode surfaces amongst other applications. Soft landing can also be used in material synthesis for creating nanoclusters, patterning surfaces, and doing high purity isolations of ionizable species.
