Hello Nicholas, nice video! We also use Bruker EDS detectors on several machines and Esprit is not the easiest software to use, imo. In the end you mentioned that you can not come back to creating the elemental maps, which I was suprised as offline analysis after the microscope session is one of the main advantages of spectrum image data cubes (less time trying to rearrange the - ever changing - map colors, more time for actual aquisition of data during the session). Under the "Hypermap"/"Mapping" menu, above the composite image one of the two menu buttons should allows us to save the whole map data as a .bcf (Bruker file format) or "raw" (.rpl) file. Even if one does not have offline licenses for Esprit, one can use open-source software packages to open these files. You can check out the "HyperSpy" project: It can open .bcf directly and do more sophisticated analysis on the EDS spectrum image compared to Esprit (e.g. denoising with principal component analysis). However, Esprit is still nice for quick analysis. Best regards and keep up the good work!
Hi TheLukmuk: the functionality to rebuild the maps/lines from the data was unfortunately not included in our purchased version of ESPRIT, which is a shame, because it really is as you rightly point out, very useful. Thank you for pointing some other possible programs for this, I will be sure to check those out. I agree that ESPRIT isn't the greatest EDS software, but it is a substantial improvement over TIA. It would be really nice if the EDS could be integrated into Velox so there would be one less program to use, which I think is an option on some systems depending on detector configuration, but unfortunately not ours.
hope you can do the followings in the future 1. comparison of single point EDS spectrum and EELS spectrum 2. comparison of large region EDS mapping and EELS mapping 3. comparison of atomic resolution EDX mapping and EELS mapping in term of how long it takes, spectrum/image resolution, damage to lamella, lamella thickness requirement, restriction to heavy/light elements, qualitative/quantitative data analysis etc. Thank Nicolas for uploading nice video with explanation Pleas keep uploading good work in the future

Me too. Looking forward to watching eels operation and analysis
