Advances in Experimental Techniques for Mercury Intrusion Porosimetry

  • Douglas N. Winslow


In 1921 Edward Washburn published an elegantly brief note in the Proceedings of the National Academy of Sciences.(1) In the space of less than one small page he laid all of the groundwork for the experimental technique that has grown, over the ensuing 60 years, into the field of mercury intrusion porosimetry. Washburn pointed out that mercury will not voluntarily enter the pores in most materials and that pressure is required to induce it to do so. He derived a simple equation, the Washburn equation, that relates the required pressure and the size of pore being entered.
