The mass spectrometry primer
SpletNo. Ion pumps need a roughing pump able to reach 1x10 -4 mbar to be started. To ensure a longer lifetime, it is recommended to start an ion pump at pressure of 1 × 10 -6 mbar or lower. This is typically achieved using turbomolecular pumps as roughing pumps. The life of an ion pump strictly depends on the operating pressure.
