Evacuation of a chamber where gases and vapors are evolved

4 Evacuation of a chamber where gases and vapors are evolved 

The magnitude of the allowable temperature for the bake-out process in question will, indeed, be determined essentially by the material in the chamber. Precise pump-down times can then be estimated by calculation only if the quantity of the evolving and pumped vapors is known. Flowever, since this is seldom the case except with drying processes, a quantitative consideration of this question is abandoned within the scope of this publication.
