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 from a "spot" size (10-80 nm) to 1μm probe diameter or larger (depending on the application and material). Detection limits range 5-100 ppm, depending on the element and settings. High analytical resolution at a 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)
- Cathodoluminescence (CL) imaging; Panchromatic Cathodoluminescence Detector is integrated within the EPMA software and can acquire individual, high-resolution CL images (grayscale or fake colors), or can be used synchronously with the WDS mapping.
- High-resolution chemical mapping of specimens on scales from <100 nm to ca 8 cm, quantitative element maps, phase map analysis
- Imaging specimens at a micro- and nano-scale scale using backscattered electron (BSE) and secondary electron (SE) signal
- Remote access and operation of EPMA-contact Gabi at g.costin@rice.edu for details on booking, sample drop off, sample delivery, remote operation instructions)
