New System: a part of ELMINET Graz
Yesterday the ELMINet Kick-off-Meeting took place. ELMINet is short for Electron Microscopy Network. It is a joint initiative of three universities to unite their expertise in the field of correlative electron microscopy. The Graz-wide network enables access to new instruments thereby opening options for interdisciplinary research cooperation. The kick-off-meeting was organised as a tour to the three different facilities, starting with opening words and impulse talks and a lab tour at the Department of Cell Biology, Histology and Embryology. Lab presentations and live demonstrations took also place at Plant Sciences (University of Graz) and Institute of Electron Microscopy and Nanoanalysis (FELMI, Graz University of Technology). At the FELMI the newly installed microscope Raman-SEM plus EDX (please scroll down for further information) was presented as well as our microtomy.

All in one: SEM & Raman & EDX = RISE + EDX
The new microscope features a fully integrated fast confocal Raman microscopy capability within the SEM chamber without any sacrifice on SEM specifications, operating independently and allowing correlated imaging between SEM (BSE-SE), EDS and Raman for structural and chemical information without complicated manipulation of the sample.
RISE stands for Raman Imaging and Scanning Electron microscopy. The seamless combination of the two techniques offers a distinct advantage when investigating samples, improves ease-of-use and accelerates experimental workflow.
This combination is the first installation in central Europe. We have already generated fascinating images and data. Please find some examples!

Raman: Cement Powder Particle Analysis
The combination of the depth of focus and material contrast of the SEM (BSE) with the depth resolution and chemical sensitivity of the confocal Raman microscope makes this analysis of particles in a powder without any sample preparation possible.
