4. Summary of Test Method
4.1 The total pore volume of a catalyst or catalyst carrier is
determined as the difference between the particle volume and
the true volume, measured by mercury intrusion and helium
pycnometry, respectively. The particle volume is determined
by mercury intrusion at ambient pressure and the true volume
is determined by helium displacement at pressures above
ambient.
5. Significance and Use
5.1 This test method provides for the measurement of
volume of pores that are in the range of catalytic importance
and possibly for adsorption processes. This test method re-
quires the use of mercury in order to perform the measure-
ments.
