Rice University Electron Microprobe Laboratory is equipped with the state-of-the-art JEOL JXA 8530F Hyperprobe, a field emission Electron Probe MicroAnalyzer (EPMA).
Electron microprobe analysis provides precise quantitative chemical analysis of elements in very small volumes (<1 to 10 μm3 or more) of solid inorganic specimens.
The capabilities include:
- Full quantitative analysis. All detectable elements (from Be to U) are quantified on a spot of <100 nm to 1μm diameter or larger. Detection limits range 30-100 ppm, depending on the element and settings. High analytical resolution at low accelerating voltage (2-10 kV), where micron scale particles can be analyzed.
- Rapid qualitative analysis, in EDS or WDS mode and phase identification
- Line analyses (rapid compositional profiles)
- High resolution chemical mapping of specimens on scales from <100 nm to ca 8 cm, quantitative element maps, phase map analysis
- Imaging specimens at micro and nano-scale scale using backscattered electron (BSE) and secondary electron (SE) signal
The EPMA facility is open to users from all departments of Rice University, as well as to external academic visitors, non-profit organizations, government agencies and local and national businesses.
