If you require ultrahigh vacuum (UHV) pumping (pressures lower than [10.sup.-9] torr), there are only a few types of pumps that will get the job done. Of these, only the ion pump can pump to pressures lower than [10.sup.-11] torr.
Ion pumps provide contamination-free operation, pump all types of gases, and have long operating lives. They also provide high pumping speeds, fast starting, and stability; require no water or liquid nitrogen for operation; consume little energy; and have no moving parts to require maintenance. Additionally, an ion-pumped system does not lose vacuum during a power failure nor does it require rejuvenation or costly cleanup after power is ...
