MERCURY POROSIMETRY
2
Mercury Intrusion Porosimetry is a pore size measurement technique based on the physical principle that a
non-reactive, non-wetting liquid will only penetrate fine pores when a sufficient pressure is applied to allow it
to intrude. There is a well-known relationship that describes the pressure required to force liquid mercury into
pores of specific diameter called the Washburn Equation:
Measuring the volume of mercury that is intruded into a sample as a function of increasing pressure permits
the generation of pore size and pore volume distributions for pores accessible from a material's exterior.
Using instruments capable of measurements at pressures between 0.2 and 60,000 psi, like the POREMASTER) 2h
Series, pores between 3.6 nanometers and 1100 microns may be measured.
Operation
A sample is placed into a measuring assembly comprising of an empty glass sample cell, an electrode, and
housing for installation into the POREMASTER !e?

As pressure increases smaller
and smaller pores will accept
liquid mercury.
The resulting volume change
along the stem of the measuring
assembly can the be plotted as a
function of pressure.

Software
Control of porosity in terms of pore volume, size, and their distribution is important for hundreds of industries,
products, and processes. The POREMASTER
) 2h
Series of mercury intrusion porosimeters comes equipped with
user-friendly PoroWin software for instrument control, data acquisition, and data interpretation. Using the Washburn equation, this data set can
be converted into a cumulative curve of the
amount intruded as a function of pore size.
The derivative of this curve provides a pore
size distribution of the pores accessible via the
exterior of the material.

Applications
Control of porosity in terms of pore volume, size, and distribution is important for a myriad of industries,
products, and processes. Quantachrome mercury porosimeters have served quality control and research needs
for characterization of materials in a wide variety of industries. The widespread appeal of this technology is
due mostly to the speed and high resolution of the measurement for the very broad range of pore sizes that
may be explored.
Battery Components
The capacity of electrolyte and
transfer properties throughout
batteries is described by the
porosity of their components.
Bone and Dental Studies
Porosity is important for
promoting bone and tooth
growth and decay.
Catalysts
The transport of reactants to and
products from active catalyst sites
occurs through pores. See ASTM
Methods D4282-12 and
D 6761- 07"%?B 2 012@??P .
Ceramics and Refractories
Structural properties and curing
proA0pVles are optimized through
the control of pore size and pore
volume.
Filtration Media
Mechanical properties such as
capacity, strength reliability
are functions of pore volume
distribution.
Medical Devices
Pore structure is important to
ensure desired isolation and/or
growth rates into biocompatible
components.
Papers and Pigments
The pore structure of coated
papers has a major impact on
their surface appearance and
print-ability.
Pharmaceuticals
Tablet mechanical and dissolution
properties are controlled via their
pore size and pore volume.
Polymers
Measure the size and volume of
porous polymers and to detect
structural changes arising from
high intrusion pressures.
Soils and Rocks
The porosity of soils and rocks
assist in understanding of
gaseous and liquiagow and
capacity. See ASTM D4404-10.
