Acquired in 1997, our reliable cold field emission SEM is capable of high resolution imaging, including backscatter imaging or z contrast to study anything from nanoparticles on tissue to different phases on geological samples.
The Hitachi S-4700 has many useful capabilities for Missouri’s investigators. With an accelerating voltage ranging from 0.5 to 30kV, it is possible to get a resolution of 1.5nm. In addition, the specimen stage is capable of tilting anywhere from -5 to 360 degrees in a continuous rotation and can accommodate a specimen up to 150mm in diameter. With multiple scanning modes maxing out at 40 frames per second, it is possible to get the perfect image to get your next grant or put in your next paper.
