The PHI VersaProbe XPS Microprobe is a multi-technique, ultra-high vacuum surface analysis instrument that is capable of producing focused, highly monochromatic X-ray beam that can be scanned over a sample surface. The spot size can be varied between less than 10 µm (for highest spatial resolution) to 100 µm (for highest sensitivity). The field of view can be as large as 1500 µm by 1500 µm. Software for surveys, high-resolution scans, sputter depth profiles, line scans, chemical images, automated analyses, and user-defined settings are all available on multiple workstations in the laboratory. The software library allows for post-analysis data processing. Elemental limits of detection of 3-4 atom % are routinely achieved.
The VersaProbe 5000 is equipped with:
Possible applications include:

Usage Fee:
Unassisted: $16/hour (academic)
$169/ hour (industry)
Assisted: $51/ hour (academic)
$409/ hour (industry)
Data Analysis Fee:
Time assessed based upon measurement/analysis time. Time begins upon the initialization of the x-ray source. Users are not charged for pump-down time. Special/extensive sample preparation needs are addressed on an as-needed basis.
All requests for instrument time must be made at least 3-full days prior to requested date.
