Argon in the tube?

Has anyone ever tried filling their open tube with Argon? My RC8 is fairly airtight at the back end, with only a few gaps around the focuser. If I trickled argon into the tube, it should initially displace the humid Sydney air. Does anyone know how long it would take to become damp argon? or might it be a good solution to dew on my sensor?
