Results of non-destructive instrumental analysis. XRF-, FTIR-spectroscopy and microscopy

  • Confronted with indications that the SNML could be a forgery, we reviewed data from our previous analyses again and supplemented it with additional readings. Again, we were short of time. During the first measurement campaign we employed X-ray fluorescence analysis to identify specific trace elements and thereby characterize different writing and drawing materials. In the new measurement campaign, we once again carried out an extensive X-ray fluorescence analysis. In addition, this time we also employed reflection infrared spectroscopy and confocal microscopy. As with earlier measurement campaigns, we were determined not to take samples. Throughout the process, we have continued to regard the object in question as unique, and as such not to he physically altered in any way. Throughout the analysis, however, it has been clear that non-destructive testing provides less comprehensive results than methods that require testing physical samples.

Throughout the analysis, however, it has been clear that non-destructive testing provides less comprehensive results than methods that require testing physical samples. The examinations described below were carried out not only on the SNML, but also on reference objects. The most important of these in this framework was the SN Graz, which is generally accepted as authentic. The following illustrates the results of the analysis in detail.zeige mehrzeige weniger
