Our facility is currently equipped with two ESCA systems and one SIMS system. The monochromatized ESCA systems, a Surface Science Instrument permit high-resolution analysis in an area on a surface down to a spot size of ~ 25 μm. The information that can be obtained from ESCA analysis includes identification and quantification of all elements present on the surface (to a depth of approximately 100Å), information about the molecular bonding environment of those elements and, using special algorithms, distributions of components of interest into the surface (depth profile). These instruments are equipped to examine specimens in a hydrated (frozen) condition, if necessary. Image samples with spatial resolutions down to approximately 10 microns. Complete computer interfacing permits flexibility in data output and analysis. The surface analysis laboratory also has space and equipment available for sample preparation.
