FEI Titan 80 – 300kV FEG S/TEM

The FEI Titan 80 – 300kV FEG S/TEM (Scanning / Transmission Electron Microscope) is a powerful instrument capable of high resolution S/TEM imaging and nanoscale analytical materials characterisation. It is equipped with an EDAX EDX detector and a Gatan Tridiem spectrometer for EELS and EFTEM. These analytical capabilities provide information on a material’s chemical composition, ideally suited to materials qualification, nano-metrology, device testing and characterisation of a wide variety of nanoparticles and chip based materials. Within the AML, the Titan acts as our high end analytical S/TEM. Combined EDX/EELS capabilities in STEM mode, and EFTEM, make it a powerful tool for local nano-compositional analysis. It also acts as a screening instrument for our Nion UltraSTEM 200. These capabilities are supported by our suite of sample preparation instrumentation.
