Limitation Factors of Vacuum
Vacuum pressure is limited by the following three factors.
- Carrier gas: Depends on analytical parameters.
- Gas desorption from the surface of the chamber and parts: Decreases slowly. It takes much time for this contribution to decrease.
- Limitation from pump performance. Usually, pressure less than 10-3 to 10-4 Pa is required near the rod and the detector
