Specific surface areas and pore volume distributions are often determined using gas adsorption techniques. Prior to analysis, any adsorbed gas or vapor phase (such as water or other volatiles) should be removed from the sample. This process is often referred to as degassing the sample.
Degassing usually involves either heating the sample or flowing an inert gas across the sample during evacuation. In either case, molecules being desorbed from the surface of the sample are removed from the sample tube.
