POROSIMETRY TESTING

Today, we received a request from an engineering university researcher for porosimetry testing.  Porosimetry analyzes a material’s porous nature and quantifies properties such as pore diameter, total pore volume, surface area, and bulk and absolute densities.

According to wikipedia’s porosity page,  the force balance equation known as Washburn’s equation for the above material having cylindrical pores is given as:[

P_L - P_G = \frac{4 \sigma \cos \theta}{D_P}
P_{L} = pressure of liquid
P_{G} = pressure of gas
\sigma = surface tension of liquid
\theta = contact angle of intrusion liquid
D_{P} = pore diameter

Porosimetry is measured by a porosimeter.  There are several different types of porosimeters including mercury porosimeters, helium porosimeters, and gas porosimeters.  Laboratory manufacturers and suppliers of Porosimeters include Thermo Electron and Steinel.
