POROMETER also supplies equipment for both liquid and gas separations. On of them is the Liquid permeability tester (LPT400), designed to determine the liquid permeability and the Silt Density Index (SDI) in technical materials in a pressure range between 50 mbars and 4 bars.
In addition, POROMETER cooperated with the Center for Surface Chemistry and Catalysis at KU Leuven to develop expertise in membrane testing in High Throughput (HT) mode.
There are numerous factors that can influence the membrane performance. On the one side, the physicochemical characteristics of a membrane depend on both compositional (e.g. solvents, polymer concentration, additives, etc.) and non compositional parameters (e.g. evaporation time and temperature, annealing time, etc.) involved in membrane synthesis and post treatment. On the other side the test conditions (temperature, pressure, feed concentration, etc) play a very important role in order to achieve the best results in a particular application. Multi-parameter screening and optimisation of these variables often requires high time, effort and capital investment.
Compared to the traditional approach of running individual tests, HT offers the following advantages:
