Polymeric membranes – Application note
Polymeric membranes are widely used in many filtration processes. The degree of selectivity of a membrane depends, amongst others, on the membrane pore size and pore size distribution. Therefore, the correct determination of pore sizes and pore size distribution is vital.
Gas-liquid and liquid-liquid porometry are exceptionally well suited for measuring polymeric membranes. Both flat sheets and hollow fibres membranes can easily be analysed with these techniques. Given its accurate determination and correct representation of pore sizes, it’s no wonder that our POROLUX™ and POROLIQ™ porometers are the most wanted brand in membrane labs worldwide.
