Mass Spectrometer and Pump Question for Mizuno Replicators

Thomas Kaminsky posted this question today, and I thought it would be helpful to put it in a separate thread, as responses could be helpful to people trying to replicate the Mizuno experiment:

Thomas asks:

“Does anyone have any ideas about how to get the Mass Spec analysis of the bake out done? Do we have to purchase/rent one? Also, is a roughing pump sufficient for the bake-out period, or does one also need a harder vacuum?
