Stainless steel vacuum pump requirements for pumping

The stainless steel vacuum pump can be used to pump air to reduce the pressure, but what are the requirements for pumping? 

Combine the pumps correctly. Due to the selective pumping, sometimes a stainless steel vacuum pump can not meet the pumping requirements, and it is necessary to combine several pumps to complement each other to meet the pumping requirements. For example, a titanium sublimation pump has a high pumping speed for hydrogen, but cannot pump helium, while a tripolar sputtering ion pump (or a two-pole asymmetric cathode sputtering ion pump) has a certain pumping speed for argon, both Combined, the vacuum device will get a better vacuum.

In addition, some stainless steel vacuum pumps cannot work under atmospheric pressure and require pre-vacuum; some stainless steel vacuum pumps require a backing pump because the outlet pressure of some stainless steel vacuum pumps is lower than atmospheric pressure, so they need to be combined.
