Table 5 is a summary of the most abundant elements present in these treads and polymers that are detectable by PIXE spectroscopy.
PIXE data suggest that the elastomer in both layers of treads #1 and #2 is probably natural rubber since a very high level (1140 ppm) of titanium (4.
A second application of PIXE spectroscopy to rubber analysis is the detection of relatively high silicon (1.
PIXE analysis further provides quantitative information on the zinc (8.
One limitation is that PIXE information is only elemental in nature, thus for example, while the presence of sulfur is measured quantitatively, it can originate from a variety of sources such as powdered sulfur ($8), accelerators or impurities.

Using modern techniques such as CT scanning, DNA testing and PIXE analysis on Tycho Brahe's remains, a team of Danish and Czech researchers, under the leadership of medieval archaeologist Jens Vellev, hopes to gain as much reliable information as possible relating to the scientist's health and medical history.
The inks and pigments used have not been analysed, although, as Ruwet notes, the advent of PIXE (proton-induced X-ray emission) non-invasive and non-destructive analytical methods now make this possible; given the syncretic nature of the document in other ways, it would be of great interest to see whether European inks and colours were used at all, or whether even the Spanish glosses were written with traditional Mesoamerican materials.
