The Thermofisher Tecnai Osiris is a modern analytical 60-200 kV scanning/transmission electron microscope (S/TEM). Its constant-current lens design delivers rapid access to high resolution TEM and STEM imaging with minimal alignments.  The Osiris is equipped with an industry-leading energy dispersive X-ray spectroscopy (EDS) SuperX™ detection system, achieving highest efficiency detection of all elements down to and including boron. Drift-corrected STEM-EDS maps utilizing this system enables quantifiable chemical imaging at the nanoscale. In conjunction with the Fischione 2020 Advanced Tomography Holder, 3D TEM, STEM and STEM-EDS imaging at the nanoscale is possible. Further, structural dynamics can be visualized utilizing the in-situ heating abilities available with the use of the Protochips Aduro Platform or Gatan In-situ heating holder.
