It is used to sterilize some materials. There are three xylenes: m-xylene (CASR# 108-38-3), o-xylene (CASR# 95-47-6), p-xylene (CASR# 106-42-3), since their molecular formula is the same they are ...

If this is done precisely, it is possible to determine the elemental composition. If there are isomers with strongly different structure, then there is a good chance to get information about this. E.g ...
