Main Question or Discussion Point

Hello
I am currently performing an interesting physics experiment and am in need of a gas that is easily accessible and can easily be ionized by someone with basic equipment. Any help would be greatly appreciated.

I think air will serve the purpose. You need say 5kV to do it and a good vacuum pump to obtain low enough pressure.

But isn't air composed of multiple different gases? It is important that there only is one gas in the chamber. (Ofcourse if there is 98% of one gas and 2% of another gas in this chamber that wouldn't be an issue)
