WebThe outgassing rate is measured in quantity of gas (pressure x volume) per unit surface area per unit time. Common units are Torr-Liters/cm 2 -s or Atm-cm 3 /cm 2 -s. Knowledge of the outgassing rate is required to relate the ultimate pressure that will be achieved in a chamber to the pumping speed.

Weband then at 250 °C with the outgassing rate evaluated after each bake. The 150 °C bake reduced the outgassing rate ~ 40% below that measured following the 400 °C bake. The reduction in outgassing rate due to the 150 °C bake is larger than would be expected due to hydrogen depletion through diffusion during the low temperature bake.
