I’ve never used Rubidium but you may want to contact dex.php for their advice and a MSDS.  They look like a good place to start.

Subject: [DCHAS-L] Rubidium Question

We have researchers here who would like  to clean out rubidium that has accumulated in a laser chamber currently filled with argon.  The rubidium has been building up for awhile in the chamber, and the lab users are concerned about it interfering with their experiments. They want to remove a device from the chamber that has the rubidium build-up on it, and then clean it separately from the chamber.  We suggested using a glovebag, but we are not sure if we can fit this around the chamber in an airtight fashion.

One of the options that the researchers proposed was to  oxidize the rubidium slowly, rendering it inert, perhaps using IPA. 

Does anyone have comments about this suggestion?  Or, any other ideas or experience with rubidium re exposure to air?

Thank you
