Dear Dr. Tan,
Generally speaking, metal does not allow light in. Everything is reflected off the surface, which means SCiO won’t have any molecular fingerprint when scanning a piece of metal and the current configuration of SCiO most likely won’t support metal detection or metal toxins in matters.
As for gas scanning, SCiO is not designed for the scanning of gaseous materials. The reflectance of them is too small and they are usually very diluted. This would require a very long optical path in order to receive a decent signal.
