Saturn 2200 has not been manufactured since 2006. It was replaced by the 220 MS which was purchased by Agilent and discontinued in 2013.
The good news? ---
Fortunately, Agilent will is required to maintain parts for the 220 ms until 2017. The Saturn 2000 uses many of the parts that the 220 MS does including all the trap and mechanical parts.
The bad news? ---
Unfortunely the electronics were updated on the 220 so most of the electronic components on the Saturn 2000 are no longer available. The Saturn 2000 is out of it's official manufacturing support period.
