Nano3 Talos TEM Service

TEM Sample Image


The Talos F200X Scanning/Transmission Electron Microscope (STEM)combines high-resolution S/TEM and TEM imaging with energy dispersive X-ray spectroscopy (EDS) characterization with compositional mapping using 4 in-column SDD Super-X windowless detectors. The Talos F200X can perform EELS by using Gatan's Enfinium ER (977) spectrometer with UltraFast DualEELS spectrum (simultaneous acquisition of low-loss and core-loss spectra).
