The fully automated noble gas processing system for MS3, our combined noble gas and helium isotope analysis system. The round grey units are computer controlled pneumatic actuators for the UHV valves. To the left is the "automanifold" where samples are mounted in groups of 8 for processing. Sixteen samples can be mounted for unattended operation of the system. The three vertically oriented "silver" cylinders near the center of the picture contain the programmable cryogenic traps.
