Description
The PMI Mercury/Nonmercury Intrusion Porosimeter is a versatile and accurate instrument used to determine properties such as pore size distribution, total pore volume, surface area, and bulk and absolute densities of solid and powder samples. With unlimited user-defined data-points, automated data collection and reduction, and the least mercury exposure of any porosimeter on the market, PMI's Mercury/Nonmercury Porosimeter is safe, reliable, and precise.
Principles of Operation
The PMI Mercury/Nonmercury Intrusion Porosimeter uses mercury intrusion or intrusion of any other nonwetting liquid to determine pore volume. The Mercury/Nonmercury Intrusion Porosimeter fills the penetrometer and sample chamber with mercury under vacuum and takes a volume reading. The sample, however, is not initially intruded with mercury or other nonwetting test liquid because of the high surface tension. Gradually, increasing amounts of pressure are applied on the nonwetting liquid. For each incremental increase in pressure, the change in intrusion volume is equal to the volume of the pores whose diameters fall within an interval that corresponds to the particular pressure interval.
