Over two years ago, CPG purchased a Zeiss EVO LS15 environmental scanning electron microscope. This instrument has become a work-horse for root-cause analysis, surface topographies and (through the attached Oxford EDS) elemental mapping. With the large chamber and capability to run in “wet mode” (hydrated at elevated pressures) it has also proved invaluable at imaging hydrogel structures and friable materials such as foods and tissues.
As part of an effort to improve the resolution of the instrument, CPG recently procured a Herzan AVI-400 antivibration solution. The entire SEM system sits on this active vibration damping system, removing virtually all of the building and environmental vibration. We are delighted that the Zeiss now achieves resolutions close to the ideal specifications of the instrument.
