AN 129 CORRECT PENETROMETER CONSTANTE

Using the Correct Penetrometer Constant with your Mercury Porosimeter

When performing mercury porosimetry analyses, it is important to use the correct penetrometer constant. The penetrometer stem holds the quantity of mercury that will be forced into the pores of the sample during the run. Since the exact pore volume that has been filled at each pressure reading is needed, it is necessary to know the change in the electrical capacitance as a result of the volume of mercury entering or leaving the stem.
