Membrane Permeation Analysis (MPA)
Traditional permeation testing is slow and fragmented, with one gas/vapor analysed at a time, limiting insights and extending analysis times. Membrane Permation Analysis removes this bottleneck by delivering multi-component data in a single experiment, eliminating the need for multiple instruments to make faster, more confident decisions.
What is Membrane Permeation Analysis?
Membrane permeation analysis is a method used in polymer and separation science to evaluate the transmission rates and competitive permeation of gases and vapors through membranes and barrier films, to assess how well these materials function under real-world conditions
- Global Application
The MPA Horizon transforms permeation analysis by enabling simultaneous measurement of multiple gases and vapours with high precision. Advanced sensors for oxygen, CO2, humidity and organic vapors allow for concurrent measurement of distinct gas and vapour transmission rates.
How does MPA work?
In a typical membrane permeation analysis experiment, a membrane of selected radius is introduced to a controlled gas and vapor mixture to one side of the membrane under continuous flow. A sweep gas continuously sweeps the other side of the membrane and carries any gases or vapours that permeate through the membrane to the outlet sensors which track the changing concentrations at the outlet.
