Electrochemistry SuiteTEM Tomography

Hummingbird Scientific’s Tomography holder is an important characterization tool in the electrochemistry suite that allows to perform pre or post-mortem analyses of battery materials in great details. Because the system permits unusually high tilt angles, the sample itself is the only contributor to the missing wedge. A range of removable tips are available for the system and can be customized for specific specimen support geometries. Specifically, any cycled samples on chips from the in-situ liquid/gas cell holders can be easily transferred and placed in the dedicated Tomography tip for analyses.
