| Outline of Final Research Achievements |
We developed a technique for producing a stable electrospray of aqueous solution in a vacuum, and designed the prototype of a vacuum-type electrospray droplet ion (V-EDI) gun for surface and interface analysis. The V-EDI gun was connected to a triple-focus time-of-flight analyzer, and the secondary ion yields of some biomolecular samples produced by the V-EDI beams were measured. The secondary ion yields by the V-EDI beams were much enhanced than those by Ga ion beams. In addition, the biomolecular samples were etched by the V-EDI beams with less damage. From those results, the high resolution 3D imaging mass spectrometry could be realized by using the V-EDI beams.
