The availability of financial resources in countries with growing economy is limited. For this reason, the acquisition of high cost equipment in each of the institutions dedicated to research is greatly restricted. High resolution transmission electron microscopes (HRTEM) are sophisticated equipment and with high-cost in the market, which are widely used in the characterization of nanomaterials. In this work, we present the remote operation of a HRTEM, discussing some technical details, results, advantages and disadvantages. The remote operation used for this paper was done with a distance between the HRTEM and the remote operator about 660 km. The remote control unit is connected to the Internet 2 with a bandwidth of 10 MB. Access to the operating functions is performed using dedicated software and a VNC connection. For one labor year, there have been analyzed more than 100 samples, obtaining high resolution images, energy dispersive x-ray spectroscopy mappings, diffraction patterns and electron energy loss spectroscopy spectra. Some of these results have been already published in scientific journals. In spite of very good results obtained, some disadvantages may be mentioned, like there are some functions for which the remote operator has not access, such as the IS2 lens, the rebooting of the lenses and obviously the sample exchange. However, the great advantage in this type of operation is that the researchers or students do not need to travel in order to analyze their materials. [ABSTRACT FROM AUTHOR]
