We often get questions about our EDS-WDS integration package for full quantification on EPMA instruments.
Currently we integrate
Probe for EPMA with both the
Bruker Esprit and
Thermo Pathfinder SDD EDS systems. Both EDS systems are excellent and allow one to acquire a full EDS spectrum for each WDS point analysis on both Cameca and JEOL EPMA instruments.
One can then specify elements by EDS to be fully quantified using standards along with the WDS elements using these already acquired EDS spectra, both on-line and off-line, for quantitative data re-processing on any computer. See here for more details, particularly the more recent postings for more up to date examples:
https://probesoftware.com/smf/index.php?topic=79.0We are currently waiting for JEOL to release their final EDS API package and then we will be ready to offer a similar integration with JEOL EDS systems. The JEOL EDS API has been tested in Probe for EPMA by Glenn Poirier at the University of Ottawa and it already works fine for integrated quantification, but there were one or two remaining minor tweaks that JEOL needs to finish and then it will be available for general use by customers with Probe for EPMA and JEOL EDS systems. The last word that we heard from Vern Robertson at JEOL is that their EDS API is finished and ready to ship with all new instruments, they are simply waiting for the export license for the software release.
When an EDS detector is integrated with Probe for EPMA one can acquire a full EDS spectrum from either the Bruker or Thermo SDD EDS detectors, which is automatically saved by Probe for EPMA to one's current probe database for quantification of both WDS and EDS elements together. By storing the *full* EDS spectrum for each point analysis on both standard and unknown acquisitions (and also wavescan acquisitions) one can add EDS elements for quantification on-line *or* off-line to improve one's matrix correction accuracy, as both the WDS and EDS elements are treated for background, matrix and interference corrections (and also the beam drift and standard intensity drift corrections) in Probe for EPMA.
And because Probe Software supports both Bruker and Thermo EDS systems, one can install either a Thermo or Bruker EDS system on either their JEOL or Cameca instrument. For example, the USGS Denver, GE Research, Exxon, University of Tasmania and University of Minnesota have Thermo EDS systems on their JEOL 8530 instruments, while the University of California at Santa Barbara, Texas A & M University and Bosie State University have Thermo EDS systems on their Cameca EPMA instruments. Similarly, the USGS Reston, University of Calgary and the Natural History Museum of Vienna have Bruker EDS systems on their JEOL EPMA instruments.
The point being that one can install either EDS system on either EPMA instrument for full integrated EDS WDS quantitative analysis!
We should also mention that there is a slight asymmetry of our re-seller agreements with Thermo and Bruker. Bruker allows Probe Software to re-sell their Esprit SDD EDS systems with our EDS WDS software integration, or one can order a Bruker EDS system directly from Bruker and with our EDS WDS integration package for JEOL or Cameca instruments.
With Thermo, Probe Software cannot re-sell their Pathfinder SDD EDS system, but Thermo can provide their Pathfinder EDS system with our EDS WDS software integration for JEOL or Cameca instruments.
And of course one can purchase either a Bruker or Thermo EDS system integrated with Probe for EPMA when purchasing a new EPMA instrument from either JEOL or Cameca.
Please let us know if you need additional information on the EDS WDS quant integration with Bruker, Thermo or JEOL EDS systems.
