Preferred Label : helium dead-space;
Detailed label : helium dead-space in colloid and surface chemistry;
IUPAC definition : The position of the Gibbs surface is often defined experimentally as that surface
which encloses the volume of space from which the solid excludes helium gas (the so-called
helium dead-space), and is associated with the assumptions that the volume of the
solid is unaffected by the adsorption of component strong i /strong , and that helium
is not adsorbed by the solid. This requires that the measurement of the helium dead-space
be made at a sufficiently high temperature.;
