I was wondering if anyone has had experience with performance of Varian
Starcell pumps vs Phi (Perkin Elmer, Physical Electronics) differential ion
ion pumps. The pump is to go on the extraction line of an Ar system and thus
will see the full range of gases and associated crap. Prices are essentially
equivalent and the performance specs look broadly similar, but the details
are difficult to unravel.
Any input or recommendations from other members of the board would be
appreciated.
