Is my sample suitable for automated analysis at PEMC?
The sample preparation needed for automated analysis is the same as for typical EDS analysis, and does not require any additional preparation. Although the live analysis is automated, there is a significant amount of set-up required for a new sample requiring a new classification scheme. As such, we recommend that preliminary analysis (optical microscopy, EDS, XRF or similar) is conducted to inform the user and staff member of key mineral phases present in the sample to aid in developing a classification scheme for the particular sample. This is especially important as rocks contain a great deal of variety, and a pre-existing classification scheme may not successfully characterise your sample.
It is also important to note that there are restrictions to Mineralogic analysis. Most notably, the step-size used by the software is balanced against magnification and the total size of the area to be analysed, which means that some detail and small features may be lost and should be analysed using other techniques available at PEMC. We also urge users to note that Mineralogic is only available on the ZEISS Sigma 300 VP SEM and is not available elsewhere in the university or offline. Any post-processing of data must therefore be conducted at PEMC.
