THE VACUUM SYSTEM
OVERVIEW
The pumping system produces the high vacuum required for high precision stable isotope
analysis. It also provides the high pumping speeds essential for the high gas flow rates required
for continuous flow applications.
The layout of the pumping system is shown below. The pumping system incorporates an
Edwards RV3 rotary pump that provides the backing for an Edwards EXT255 or nEXT 240D
turbomolecular pump.
