KORE Surface Seer

Location Chemistry, University of Birmingham
Custodian Professor Jon Preece
Applications The Surface Seer is a time-of-flight SIMS instrument dedicated to investigating the surface chemistry of materials. A focused caesium
ion beam scans an area typically 500 x 500 μm on the surface of a sample. This results in mass spectra characteristic of the very
top-most atom layers of the sample, which is of increasing importance in materials engineering, biomaterials, drug delivery, etc.
The instrument detects all elements of the periodic table from hydrogen to uranium down to ppm levels, but its real strength is the ability to provide unique information about organic compounds on surfaces, even coatings or structures just a few atom layers thick. Various surface phenomena, such as self-assembled monolayers, can be characterised.
Specification
  • Reflectron energy analyser
  • Positive and negative ion modes
  • Analysis of both insulating and conducting samples
  • Mass range >1000 m/z
  • Mass accuracy of ± 10 mamu
  • Samples must be vacuum-compatible
