Instrument and measuring principle
The pressure required to intrude mercury into the sample’s pores is inversely proportional to the size of the pores. This is called mercury porosimetry, or often, “mercury intrusion.” Using this principle a pore size distribution can be obtained.

Instrument:

  • Micromeritics Autopore IV
       Model 9520

    Parameters and applications
    Able to measure pore sizes in the range 0.003 to 360 µm. From the pore size distribution the total porosity of the sample can be calculated.

    Prerequisites
    Dependent on the total porosity of the sample. Typically 500 mg per determination.


    • Micromeritics Autopore IV.
