The OMNI Electron Microscopy unit needs a new transmission electron microscope to replace the existing 26-year-old Philips/FEI CM100 instrument in our multiuser research and training environment.

Our facility currently has a JEOL 2200FS cryoTEM, a JEOL 6700 FEG SEM, and a recently installed Zeiss Sigma SEM with an Oxford EDS system and Gatan 3View serial block face system. We work closely with the OMNI Confocal Microscopy unit and intend to expand our capability to include correlative light and electron microscopy techniques. The facility is equipped with conventional sample preparation and cryo-preparation instruments including a Leica EMPact 2 high-pressure freezer and a Vitrobot.

There is a major gap in specimen analysis capably at Otago University (and New Zealand) that we would like to take the opportunity to address with the replacement 120kV TEM. This is the ability to do fine elemental analysis using energy dispersive spectroscopy (EDS) on ultrathin biological and non-biological specimens (both conventionally prepared and cryo-prepared), including microcrystals and nanoparticles.

This capability will benefit scientists from a wide range of research fields, including material sciences, chemistry, geology, archeology, food science, microbiology, botany, neuroscience, and toxicology. Nanoparticles, micro-crystals, and cellular components are typical examples where compositional information is increasingly becoming crucial for publication in high-impact journals. The addition of cryo-imaging capability on the new TEM will also enable frozen samples to be analysed or screened prior to imaging and electron tomography in the JEOL 2200FS cryoTEM.
