What is the unit ml/g/um in mercury porosimetery?

  1. Jan 20, 2010 #1
    One of the outputs of mercury porosimetry is Differential intrusion in ml/g/um.
    this is ml of Hg per g of sample per um of what?
    What is that micrometer? The characteristic length of the sample, the average pore diameter or radius?.

    Also, why is there a "log differential intrusion", for which the unit is ml/g. The um have vanished but what has been log-ed?
