Strontium oxide, as is typical for group II oxides, is very basic, and will absorb CO2 readily to form surface carbonates.
If analysing strontium oxides, GCIS etching may be required to remove surface carbonates. Sr carbonate does not decompose until ~ 875 degrees Celsius, so heat treatment in vacuo is unlikely to be an option.
Strontium has no particularly unusual features that complicate fitting.
