ABSTRACT:
An apparatus for porosimetric measurements, wherein a sample to be analyzed is put in an ampoule filled with mercury and submitted to ever increasing pressures, in order to obtain measurements of the mercury volume variations due to pressure increases.
Such mercury volume variations, which are correlated to the sample pore sizes, are detected by measuring capacity variations in a mercury condenser provided for in a capillary neck of ampoule.
