Liquid-Liquid Porometry for Characterising Ultrafiltration Membrane Pores

Liquid-Liquid Porometry (LLP) is a valuable technique for measuring the pore structure characteristics of ultrafiltration membranes without damaging the membranes themselves. These membranes can act as barriers to a whole range of particles, both organic and inorganic, including bacteria, pollens, spores, pathogens and pesticides and even high molecular weight solutes, colloidal suspensions, and viruses.

Pore characteristics such as pore distribution, liquid permeability, pore throat diameter, bubble point pore diameter and mean flowpore diameter all offer valuable insights into pore function. However, capillary flowporometry a technique that can provide the required information about such characteristics uses high test pressures not suited for measuring ultrafiltration membranes. Liquid-Liquid Porometry (LLP) by comparison can measure the required pore structure characteristics without distorting the pore structure or damaging the membranes. In addition LLP is faster, uses less energy and lower pore sizes can be characterised.poro fror blog
