You need to characterize the pore structure of your product, but you’re unsure of how best to do so. You’ve done your research and found a technique called Mercury Intrusion Porosimetry (MIP) but it’s unclear if this is an appropriate test for your needs. How do you proceed?
The experts at Particle Technology Labs (PTL) are happy to guide you completely through the process. We answer commonly asked questions below for those interested in gaining a deeper understanding of MIP:
What is Mercury Intrusion Porosimetry?
Mercury Intrusion Porosimetry is a technique that utilizes mercury to probe the surface accessible pores of a solid or powder material. Mercury is an ideal probe chemical because it is a non-wetting liquid that requires external pressure to fill voids in the surface of a sample. By volumetrically measuring the quantity of mercury forced into the pores of a sample at a given pressure, we can determine the pore size, pore volume and porosity of your sample. Pore size is inversely proportional to the amount of pressure required to force the mercury into the sample pore. Large pores require less pressure to fill with mercury than smaller pores.
