Argon is absolutely inert and won't cause any reaction (read: decomposition). It's heavier than air and the first choice for such an application. It shouldn't be too difficult to obtain small pressurized bottles of argon.
Carbon dioxide can react with traces of water to form carbonic acid. This is then absorbed by basic compounds, which can lead to decomposition but doesn't have to necessarily.
Nitrogen is almost as good as argon but is lighter than air and will escape much easier. Nitrogen oxide is not recommended due to possible reactivity.
