Well, this is only sort-of possible.  The capillary nature of the plumbing
will make it difficult to get much of a vacuum on the portion of the
reactor that has the bulk of the volume, but it could be possible to reduce
the atmosphere by an order of magnitude.

Then you have to deal with the fact that this is yet another departure from
replication.  We don't really know that the oxygen, nitrogen, and argon are
not involved in the reaction.  Removing these gasses will certainly alter
the chemistry of the reaction. Neither Parkhomov nor Rossi removed the
atmosphere.  It might turn out to be something that improves the reaction,
but it is another departure from replication.
