Electron microscopes can excite electrons to form images that magnify micron and nanostructures up to 10 million times, providing amazing levels of fine magnification and allowing researchers to observe even individual atoms. CD BioSciences can provide innovative solutions for electron microscopy and microanalysis. We offer Hitachi HD2700C Scanning Transmission Electron Microscope instruments that allow customers to combine high-resolution imaging with physical, elemental, chemical and electrical analysis to obtain usable data from the widest range of samples.

The Hitachi 2700C is a dedicated Scanning Transmission Electron Microscope (STEM), operating at 80, 120 and 200 kV. It has a probe aberration-corrector, which improves imaging spatial resolution to less than 1Å. The energy resolution for electron energy loss spectroscopy (EELS) can be as small as 0.35 eV, due to its cold field emission electron gun (FEG) and the presence of a high-resolution parallel EELS detector (Gatan Enfina-ER). This instrument is ideal for probing structural and electronic properties of materials at the Angstrom level, allowing on to study the physical, chemical and electronic structure of oxide interfaces, catalysts and other functional nanomaterials. Notably, this Hitachi STEM has a secondary electron microscopy (SEM) detector for high resolution SEM imaging of the particles on the surface, with atomic resolution imaging have been demonstrated in the SEM imaging mode.
