Mercury intrusion porosimetry equipment

    I have used the Mercury intrusion porosimetry equipment to determine pore diameter range of porous ceramic material. But it only determined the micro and meso porosity. I also read that this tecnique is not adequate to determine macroporosity. Do you know Why?

    This equipment also determined pore number fraction. Can you tell me what is this?

    How do I calculate the total porosity with knowing the apparent density given by the porosimetry equipment and the real density given by the helium picnometer?

    Thank you
