When the SEM was configured for EDS (energy
dispersive spectroscopy) analysis to determine
elemental content, we were able to detect carbon
(C), oxygen (O), sulfur (S) and a calcium (Ca).
Carbon was the most predominant with sulfur
having the next highest concentration. Oxygen was
about half the level of the sulfur, and calcium
was the lowest of the four (Figure
6).
Scanning of a broader area of the sample gave
similar results but revealed, in addition, small
amounts of sodium (Na), chlorine (Cl) and
potassium (K) (Figure 7). Assuming the sample
is organic, it probably also contains a
significant amount of hydrogen, which is too
light an element to be detected.
Conclusion: The sample appears to be an organic
substance with primary detectable elements
corresponding to carbon, oxygen, and sulfur. Its
identity and possible function remain unknown at
this time.
